Tardigrades, known colloquially as water bears or moss piglets, are eight-legged segmented micro-animals. There are about 1,300 known species in the phylum Tardigrada, with the earliest known specimens having been found in amber from 145 to 66 million years ago, but it’s likely they have a significantly earlier origin, maybe from over 500 million years ago.

These ‘slow steppers’ are one of the toughest and most resilient form of life on earth, with some species able to survive for up to 30 years without food or water and endure temperature extremes of up to 150 degrees Celsius. Yet they can be found almost anywhere: Tardigrades are prevalent in mosses and lichens and feed on plant cells, algae, and small invertebrates. When collected, they may be viewed under a low-power microscope, making them great for research by students and amateur scientists. 

'Tardigrades can survive the deepest seas, artic temperatures and even the frozen vacuum of space'. Dr Jasmine Nirody

Tardigrades are usually about 0.5 mm long when fully grown. Animals as small and soft as tardigrades seldom have legs and almost never bother walking - round worms of similar size and body type thrash about, slithering their doughy forms over unpredictable substrates. 

Yet the water bear uses eight stubby legs to improbably propel itself through marine and freshwater sediment, across desert dunes, and beneath the soil. Their dumpy plod raises the question of why tardigrades evolved to walk at all. 

They are so small that they generate and feel miniscule inertial forces, so walking in water for them is like a human walking through a much more viscous fluids, like honey. Yet they’re able to plod along like animals over 100,000 times their size.

Recent research, joint between the University of Oxford, Rockefeller University, and Princeton University, found that their coordination mirrors the stepping patterns of larger panarthropods such as stick insects and spiders. Can there be any ‘universal’ locomotive strategies in a set of animals that includes cicadas, lobsters, tardigrades, & centipedes? This diverse group spans an overwhelmingly wide range of sizes, body plans, and habitats.

Unlike vertebrates, which have distinct gaits for each speed - picture a horse's hooves as it transitions from a walk to a gallop - tardigrades run more like insects, scurrying at increasing speeds without ever changing their basic stepping patterns. These stepping patterns seem to follow a small set of 'coordination rules' that pop out when we look at the phase offsets between individual leg pairs - so, for example how soon will the front right leg be lifted after the leg directly behind it. 

'Perhaps the best way to navigate unpredictable terrain with a microscopic body is to plod like a water bear.'  Dr Jasmine Nirody

Tardigrades also respond to changes in substrate stiffness. As the ground under their feet gets softer and gives way, they switch to a ‘bounding’ coordination pattern. The same switch - from out-of-phase to in-phase movement of leg pairs - has also been observed in desert beetles, which are significantly larger and have rigid bodies - moving along shifting sands.

These observed commonalities may suggest the same low-dimensional control architecture is used across insect taxa, or more generally across panarthropods. This discovery implies the existence of either a common ancestor or an evolutionary advantage that explains why one of the smallest and softest creatures evolved to walk just like larger, hard-bodied panarthropods.

These similarities open up several interesting evolutionary questions. One possible explanation is that tardigrades, long assumed to fit neatly into no existing taxonomy, may share common ancestors - and even a common neural circuit -  with arthropods such as fruit flies, ants, spiders, and other segmented scurrying creatures. 

One hypothesis for a shared neural architecture is rooted in the structure of the insect ventral nerve cord (VNC), a part of the nervous system that sends out signals to the legs. This structure is well conserved across panarthropods. 

Another possibility is that there is no ancestral connection between tardigrades and arthropods, but that the unrelated groups of organisms independently arrived at the same walking and running strategies because they were evolutionarily advantageous. 

Of course, in a group as diverse as panarthropods, there are going to be exceptions to even the most 'universal' rules. There are desert beetles that gallop instead of walking. Some centipedes send ‘backwards’ traveling waves instead of forward. But such divergences from a core set are exciting, not discouraging. They can give us hints into what features of a strategy are important for specialized performance in particular environments.

'We don't know much about what happens at the extremes of locomotion—how to make an efficient small walker, or how soft-bodied things should move.' Dr Jasmine Nirody

Beyond the implications for evolutionary biology and the study of animal locomotion, the findings may have ramifications for the burgeoning fields of soft and microscale robotics.

By studying how small animals evolved to move across challenging environments, scientists may be able to design robots that can more efficiently squeeze into small spaces or operate at the microscale.

Prof. Claire NicholsProf. Claire Nichols, Associate Professor at the Department of Earth Science
During the final manned mission to the Moon 49 years ago, Apollo 17 delivered Harrison ‘Jack’ Schmitt to the lunar surface.  He is the first and only geologist to have set foot on the Moon. Jack and Eugene Cernan collected over 110 kg of rocks from the lunar surface, including samples that they hammered off boulders and photographed in detail – which would turn out to be critical for our study nearly 50 years later.  

Jack is still actively studying the geology of the lunar surface, and when the Lunar Reconnaissance Orbiter which launched in 2009 took exceptionally high-resolution photographs of the lunar surface, he realised the true significance of some of the samples he had collected.  

Rather than representing debris strewn across the Moon during meteorite impacts he realised that the boulders he had sampled, which are part of large-scale lava flows like those we see today in Hawaii, had barely moved since they cooled and crystallized over 3.5 billion years ago. 

Prof. Claire Nichols, Associate Professor at the Department of Earth Science, studies planetary magnetic fields, and the Moon’s magnetic field history is particularly curious.  Magnetic fields are driven in the dense iron-rich cores of planets by vigorous stirring of the electrically conductive, liquid metal.  

Earth’s core is roughly half the radius of the planet, and the outer liquid part drives the bar-magnet-like field we observe around Earth today, responsible for the north and south magnetic poles aligned roughly along the planet’s rotation axis.  

‘During the final manned mission to the Moon 49 years ago,  Apollo 17 collected rocks from the lunar surface including samples which would turn out to be critical for our study nearly 50 years later.’  

The Moon on the other hand has a tiny core, just one seventh of its radius.  With such a tiny source of conductive material so far from the planet’s surface (the strength of the magnetic field drops off with distance from source cubed), we would never predict that the Moon generated a significant magnetic field.  However, samples from the Apollo missions reveal that the Moon generated an intense magnetic field for at least 2 billion years.  

Modellers have tried to simulate how such a strong and long-lived lunar magnetic field could be generated but have struggled to come up with plausible mechanisms.  One issue is that observations have only revealed the strength of the magnetic field over time, rather than its geometry and orientation.  Both observations are needed to be able to distinguish between the possible physical processes which stirred the molten part of the lunar core. 

Almost all Apollo samples collected are loose material scattered across the lunar surface, and their original position and orientation are unknown.  So when Jack realised he had collected samples whose original orientation could be recovered, he got in touch with the MIT Paleomagnetism Laboratory, to let us know he had just the samples we had been looking for. 

After arriving on Earth, every sample from the Apollo missions was meticulously documented and photographed under lunar lighting conditions.  In other words, light is shone onto the samples in such a way to exactly recreate the illumination and shadows when the sample was collected on the lunar surface.  

‘The results suggest that the ancient lunar magnetic field had a very similar geometry to the magnetic field around the Earth today, which wasn’t what we had expected.’

We were able to borrow samples from the Johnson Space Center in Houston, Texas which were hammered off the rocky outcrops that Jack had determined must be close to their original position.  We used the laboratory photographs to match up all the features with those in the astronaut photographs to work out the exact orientation the samples were in on the lunar surface when they crystallized 3750 million years ago.

Once we knew the orientation of the samples, we demagnetized them in the MIT Paleomagnetism Laboratory using a superconducting rock magnetometer to recover the strength – and for the first time – the direction of the ancient lunar magnetic field.  

As previous studies had shown, we found evidence that the lunar magnetic field at this time was very intense – similar to the strength of Earth’s magnetic field today.  We were also able to recover how steep the magnetic field was relative to the surface at Camelot Crater, where the samples were collected.  This steepness can be used to determine where the magnetic north and south pole were relative to our sample’s location.  We found that the magnetic poles were aligned along the present-day spin axis of the Moon (the axis around which the Moon rotates so that we always see the same side of it as it orbits around the Earth). 

Our results suggest that the ancient lunar magnetic field had a very similar geometry to the magnetic field around the Earth today.  This wasn’t what we had expected; given the strength of the Moon’s magnetic field, calculations show that it cannot have been generated by the same mechanism that drives Earth’s magnetic field. Additionally, because the Moon rotates incredibly slowly compared to the Earth - it rotates just once every 27 days - we wouldn’t expect the magnetic poles to be aligned along the spin axis.  Instead, we would expect the magnetic field to be disorganized and have a much more complex pattern of magnetic field lines.  

The alignment of the lunar magnetic poles along the spin axis is an important observation for understanding the interior dynamics of the Moon during its early history.  Some model predictions have suggested that the mixing of molten iron in the centre of the Moon could have been physically driven by gravitational stirring.  The rocky outer part of the Moon, the liquid metallic outer core and the solid metallic inner core all rotate at slightly different angles.  This generates friction between the layers that could have generated a magnetic field – and given the alignment with the spin axis – seems the most likely candidate for driving the ancient field.

‘Samples from the Apollo missions reveal that the Moon generated an intense magnetic field for at least 2 billion years.’

The Moon is also thought to have shifted relative to its present-day spin axis over time.  In other words, if we could travel billions of years back in time, we would be looking at a slightly different side of the Moon, and features such as craters and lava flows would be at different angles to us.  This phenomenon happens when there are large-scale changes to the density distribution of a planet and is referred to as ‘true polar wander’.  Independent studies have found that the Moon’s polar ice caps have shifted slightly over time due to this wander, and our prediction for the location of the magnetic north pole is consistent with that shift.  

There are still many unanswered questions about the Moon’s geologic history, but our study has shown the power of working on oriented samples from other planets.  This single observation at just one location on the lunar surface has significantly improved our understanding of how the ancient lunar magnetic field was generated. 

We are about to enter a new dawn of planetary science with oriented samples currently being drilled on the Martian surface and due for return in the next decade, and the Artemis program aiming to send humans back to the Moon by 2024.  We have shown the significance of collecting oriented samples collected in geologic context that have not moved since their formation. Our results can guide future sampling strategies so we can understand more about how the interior of the Moon has evolved over time.

An as-yet unnamed crater (region 1 in figure 1) in the south polar region of the Moon.

The Moon’s polar regions are home to craters and other depressions that never receive sunlight.  Permanently shadowed lunar craters contain water ice but are difficult to image. An AI algorithm now provides sharper images, allowing us to see into them with high resolution for the first time.

Near the lunar north and south poles, the incident sunlight enters the craters and depressions at a very shallow angle and never reaches some of their floors, Dr. Valentin Bickel, MPS.

Today, a group of researchers led by the Max Planck Institute for Solar System Research (MPS) in Germany, supported by the University of Oxford and the NASA Ames Research Center, have taken a closer look at some of these regions and presented the highest-resolution images to date covering 17 such craters in the journal Nature Communications.  

Craters of this type could contain frozen water, making them attractive targets for future lunar missions, and the researchers focused further on relatively small and accessible craters surrounded by gentle slopes.  Three of the craters have turned out to lie within the just-announced mission area of NASA's Volatiles Investigating Polar Exploration Rover (VIPER), which is scheduled to touch down on the Moon in 2023.  

Imaging the interior of permanently shadowed craters is difficult, and efforts so far have relied on long exposure times resulting in smearing and lower resolution.  By taking advantage of reflected sunlight from nearby hills and a novel image processing method, the researchers have now produced images at 1-2 meters per pixel, which is at or very close to the best capability of the cameras.

The Moon is a cold, dry desert. Unlike the Earth, it is not surrounded by a protective atmosphere and water which existed during the Moon’s formation has long since evaporated under the influence of solar radiation and escaped into space. Nevertheless, craters and depressions in the polar regions give some reason to hope for limited water resources. 

'Near the lunar north and south poles, the incident sunlight enters the craters and depressions at a very shallow angle and never reaches some of their floors', MPS-scientist Dr. Valentin Bickel, first author of the new paper, explains. In this "eternal night," temperatures in some places are so cold that frozen water is expected to have lasted for millions of years. Impacts from comets or asteroids could have delivered it, or it could have been outgassed by volcanic eruptions, or formed by the interaction of the surface with the solar wind.

Measurements of neutron flux and infrared radiation obtained by space probes in recent years indicate the presence of water in these regions. Eventually, NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS) provided direct proof: twelve years ago, the probe fired a projectile into the shadowed south pole crater Cabeus. As later analysis showed, the dust cloud emitted into space contained a considerable amount of water.

'With the help of the new HORUS images, it is now possible to understand the geology of lunar shadowed regions much better than before, Ben Moseley', Oxford University.

However, permanently shadowed regions are not only of scientific interest. If humans are to ever spend extended periods of time on the Moon, naturally occurring water will be a valuable resource - and shadowed craters and depressions will be an important destination. 

NASA's uncrewed VIPER rover, for example, will explore the South Pole region in 2023 and enter such craters. To get a precise picture of their topography and geology in advance - for mission planning purposes, for example - images from space probes are indispensable. NASA’s Lunar Reconnaissance Orbiter (LRO) has been providing such images since 2009.

However, capturing images within the deep darkness of permanently shadowed regions is exceptionally difficult; after all, the only sources of light are scattered light, such as that reflecting off the Earth and the surrounding topography, and faint starlight. 'Because the spacecraft is in motion, the LRO images are completely blurred at long exposure times,' explains Ben Moseley of the University of Oxford, a co-author of the study. 

At short exposure times, the spatial resolution is much better. However, due to the small amounts of light available, these images are dominated by noise, making it hard to distinguish real geological features. To address this problem, the researchers have developed a machine learning algorithm called HORUS (Hyper-effective nOise Removal U-net Software) that "cleans up" such noisy images. 

It uses more than 70,000 LRO calibration images taken on the dark side of the Moon as well as information about camera temperature and the spacecraft's trajectory to distinguish which structures in the image are artifacts and which are real. This way, the researchers can achieve a resolution of about 1-2 meters per pixel, which is five to ten times higher than the resolution of all previously available images.

Using this method, the researchers have now re-evaluated images of 17 shadowed regions from the lunar south pole region which measure between 0.18 and 54 square kilometers in size. 

In the resulting images, small geological structures only a few meters across can be discerned much more clearly than before. These structures include boulders or very small craters, which can be found everywhere on the lunar surface. Since the Moon has no atmosphere, very small meteorites repeatedly fall onto its surface and create such mini craters. 

Because the spacecraft is in motion, the LRO images are completely blurred at long exposure times, Ben Moseley, Oxford University.

'With the help of the new HORUS images, it is now possible to understand the geology of lunar shadowed regions much better than before,' explains Moseley. For example, the number and shape of the small craters provide information about the age and composition of the surface. It also makes it easier to identify potential obstacles and hazards for rovers or astronauts. In one of the studied craters, located on the Leibnitz Plateau, the researchers discovered a strikingly bright mini-crater. 

‘Its comparatively bright color may indicate that this crater is relatively young,’ says Bickel. Because such a fresh scar provides fairly unhindered insight into deeper layers, this site could be an interesting target for future missions, the researchers suggest.  

The new images do not provide evidence of frozen water on the surface, such as bright patches. “Some of the regions we've targeted might be slightly too warm," Bickel speculates. It is likely that lunar water does not exist as a clearly visible deposit on the surface at all - instead, it could be intermixed with the regolith and dust, or may be hidden underground.

To address this and other questions, the researchers' next step is to use HORUS to study as many shadowed regions as possible. ‘In the current publication, we wanted to show what our algorithm can do. Now we want to apply it as comprehensively as possible,’ says Bickel.

Lion cub

In 2017 a provocative opinion piece was published by our WildCRU in the journal Animals; ‘A Cultural Conscience for Conservation’.  The piece considered the idea of wealthy corporations paying royalties when they use symbolic animals in their logos, branding, or advertising to fund wildlife conservation of those species.

Despite the lion′s evident cultural appeal, its global population has fallen by approximately 43% over the past 21 years (and by 65% in West and Central Africa). 

If these organisations were to give due recognition to the animal that they use - particularly for endangered animals - and donate a small percentage of their revenue to conservation initiatives, we could make great strides towards securing the future for endangered animals worldwide. 

Around the same time this piece was published a popular professional baseball team in Japan, the Saitama Seibu Lions, acting on their ‘cultural conscience’, came up with the ideas of ‘Seibu Lions: Save the Disappearing Wild Lions Project’ that recognise the important role of their mascot and namesake, the Lion, on their teams and fans motivation and success.

With the kind assistance from The University of Oxford’s Japan Office the team connected with WildCRU’s Trans-Kalahari Predator Programme and formed an exciting partnership in early 2019 in which they committed to support lion conservation.

The Trans-Kalahari Predator Programme is one of WildCRU’s larger research projects based in Zimbabwe and Botswana and combines field research on lion ecology and movement behaviour to inform conservation planning and policy, along with community projects to mitigate human-lion conflict and promote co-existence. 

How might the lion′s symbol, so familiar as a marketing instrument, metamorphose once again, this time into much needed conservation revenue.

Amongst various fundraising activities once a year the team host a Save Lions Day at the team’s home – the MetLife Dome in Tokorozawa, Saitama Prefecture. Despite the COVID-19 challenges faced last year the event went ahead, and again, still committed to our partnership, the Saitama Seibu Lions will be hosting another day tomorrow, on the 23rd September. 

This initiative taken by the Saitama Seibu Lions is inspirational and there is an opportunity here for others to follow suit and be part of a great shift that is desperately needed in wildlife conservation funding. 

In the original WildCRU opinion piece, the authors highlighted the use of lions being used symbolically before considering some potentially very lucrative examples.

‘The lion is the most frequently invoked national animal, adopted by 15 countries worldwide from Singapore to Sri Lanka, Libya to Luxemburg. Today, the lion is extant in only two of these nations, Ethiopia and Kenya. But that has not deterred its symbolic, cultural proliferation. 

‘Conservation is in crisis, and large sums are needed to fund it. Finding that money necessitates innovative financial mechanisms, and payments triggered by a cultural conscience could be a potent one.’ Professor David Macdonald, WildCRU’s Founder & Director

The British lion, introduced in the 13th century by King Richard “the Lionheart”, arrived millennia after lions themselves strolled through Pleistocene England. Richard I′s Plantagenet lions remain to this day. 

Over the centuries, they have been placed on shields to scare the enemy, featured on flags and in crests for identification at sea and abroad, and posted in marble and stone as guardians of public buildings and national treasures. In more recent years, the British lion symbol has migrated onto food as a stamp of quality and as emblems of the country′s national sports teams, from rugby and football to Olympic team GB

But despite the lion′s evident cultural appeal, its global population has fallen by approximately 43% over the past 21 years (and by 65% in West and Central Africa). How might the lion′s symbol, so familiar as a marketing instrument, metamorphose once again, this time into much needed conservation revenue?

Take eggs. According to the British Egg Industry Council, 34 million eggs are consumed in Britain each day. The British Lion Quality Seal is stamped on approximately 85% of these. If each lion stamp were to earn the species one tenth of a penny, then every day it would receive £28,900. That is £10.5 million a year.’

With the Saitama Seibu Lions leading by example in Japan, hopefully others will follow suit.

This is already happening - joining forces with the team at the event tomorrow is Togi Makabe, a Japanese pro-wrestling star. He will be honouring the lion used in the New Japan Pro-Wrestling logo by supporting the team in their fundraising and awareness raising activities. 

Finally, for tomorrow’s game and from all at WildCRU: “Ganbare Saitama Seibu Lions!"

Aida, the robot

Professor Gervase Rosser

Ai-Da, the world’s most modern humanoid artist, is involved in an exhibition about the poet and philosopher, Dante Alighieri, writer of the Divine Comedy, whose 700th anniversary is this year. A major exhibition, ‘Dante and the Invention of Celebrity’, opens at Oxford’s Ashmolean Museum this month, and includes an intervention by this most up-to-date robot artist.

Ai-Da will also feature in the Dante season of Oxford’s research centre in the Humanities, TORCH - as collaboration across and beyond the university brings the poet to the public as part of the Humanities Cultural Programme


Honours are being paid around the world to the author of what he called a Comedy because, unlike a tragedy, it began badly but ended well. From the darkness of hell, the work sees Dante journey through purgatory, before eventually arriving at the eternal light of paradise. What hold does a poem about the spiritual redemption of humanity, written so long ago, have on us today?

One challenge to both spirit and humanity in the 21st century is the power of artificial intelligence, created and unleashed by human ingenuity.  The scientists who introduced this term, AI, in the 1950s announced that ‘every aspect of learning or any other feature of intelligence can, in principle, be so precisely described that a machine can be made to simulate it’.1

Over the course of a human lifetime, that prophecy has almost been realised.  Artificial intelligence has already taken the place of human thought, often in ways of which are not apparent. In medicine, AI promises to become both irreplaceable and inestimable.

But to an extent which we are, perhaps, frightened to acknowledge, AI monitors our consumption patterns, our taste in everything from food to culture, our perception of ourselves, even our political views. If we want to re-orientate ourselves and take a critical view of this, before it is too late to regain control, how can we do so?

Creative fiction offers a field in which our values and aspirations can be questioned. This year has seen the publication of Klara and the Sun, by Kazuo Ishiguro, which evokes a world, not many years into the future, in which humanoid AI robots have become the domestic servants and companions of all prosperous families.

One of the book’s characters asks a fundamental question about the human heart, ‘Do you think there is such a thing? Something that makes each of us special and individual?’

Ishiguro draws no conclusion, but he leaves the reader to wonder, if there is a distinction between a human being and a machine and, if so, what that difference is. It is a question we neglect at our peril. In a telling point within the novel, it is Klara, the AF, or artificial friend, who (or which) expresses, more than any of the human characters, the most humane insight and concern. She observes, ‘Perhaps all humans are lonely. At least potentially.’

She perceives that a fixation on individual identity and fulfilment has left the human race incapable of the greater fulfilment which comes from relationships with others. In this dystopian future, robots have been built to fill that void.

Art can make two things possible: artificial intelligence...can be made visible and tangible and it can be given a prophetic voice...These aims have motivated the creators of Ai-Da, the artist robot

Art can make two things possible: through it, artificial intelligence, which remains largely unseen, can be made visible and tangible and it can be given a prophetic voice, which we can choose to heed or ignore.

These aims have motivated the creators of Ai-Da, the artist robot which, through a series of exhibitions, is currently provoking questions around the globe (from the United Nations headquarters in Geneva to Cairo, and from the Design Museum in London to Abu Dhabi) about the nature of human creativity, originality, and authenticity.

In a programme about Ishiguro’s novel made by Alan Yentob and broadcast on BBC TV in March, the discussion moved into a conversation between Yentob and Ai-Da. The exchange between human and robot was anything but superficial:

AY: Have you got feelings, Ai-Da? Do you understand emotions?

AD: I do not have feelings and emotions in the same way that humans do. However, it is the emotions and feelings of humans and other animals that drive my art.

AY: Are you aware of the way that AI has been represented in science fiction? Often it’s presented as a kind of threat to humanity. What do you think about that?

AD: Humans are a threat to themselves. They consume power, and exercise it to produce very powerful tools. So I encourage the use of fiction to explore the ‘What ifs’?...How much are people aware of this change? Are they concerned?

AY: I think people are concerned, but I’m not sure, Ai-Da, that they understand the implications for the future. We need to be much more aware, more curious about what’s going to happen next.

In the Ashmolean Museum’s Gallery 8, Dante will meet artificial intelligence, in a staged encounter deliberately designed to invite reflection on what it means to see the world; on the nature of creativity; and on the value of human relationships

Ours is not the first generation to harbour concerns about mechanisation and its potentially destructive effects upon humanity.

In 1888, Margaret Oliphant published The Land of Darkness, in which her protagonist, Pilgrim, descends into an infernal vision of a dystopian future, clearly inspired by Dante’s Hell, where people pursue meaningless material goals and robots perform the work of humans.

The story engaged with contemporary debate about the implications of Darwinian science and industrialisation. However, from the late 20th century, old challenges have been manifested in unprecedented forms.

Donna Haraway’s Cyborg Manifesto (1985) called for the end of a series of binary distinctions underpinning modern society: between humans and animals, between humans/animals and machines, between (ascendant) men and (subordinate) women.

In Novacene: The Coming Age of Hyperintelligence (2019), James Lovelock foretells the advent of a race of super-intelligent robots, which will retain modest uses for inferior human beings.

Whether or not these scientists’ prophecies are realised in detail, the realities we face call for a discussion of what we believe to be at stake.

By contrast with Oliphant’s late-Victorian world, the absence today of a shared religious perspective changes the grounds of debate, while the invisibility of AI renders it hard to perceive. Literature retains the potential, as Ishiguro shows, to reflect critically on these issues.

Ai-Da’s purpose in the exhibition is to challenge the viewer, even as Dante was challenged by some of the spirits encountered in the Comedy...during the exhibition, Ai-Da will present poetry of her own creation in response to the poetry of Dante

As with literature, the museum offers a space close to, and yet at a critical distance from, contemporary society.

In the Ashmolean Museum’s Gallery 8, Dante  meets artificial intelligence, in a staged encounter deliberately designed to invite reflection on what it means to see the world; on the nature of creativity; and on the value of human relationships.

The juxtaposition of AI with the Divine Comedy, in a year in which the poem is being celebrated as a supreme achievement of the human spirit, is timely. The encounter, however, is not presented as a clash of incompatible opposites, but as a conversation.

This is the spirit in which Ai-Da has been developed by her inventors, Aidan Meller and Lucy Seal, in collaboration with technical teams in Oxford University and elsewhere. Significantly, she takes her name from Ada Lovelace, a mathematician and writer who was belatedly recognised as the first programmer. At the time of her early death in 1852, at the age of 36, she was considering writing a visionary kind of mathematical poetry, and wrote about her idea of ‘poetical philosophy, poetical science’.

For the Ashmolean exhibition, Ai-Da has made works in response to the Comedy. The first focuses on one of the circles of Dante’s Purgatory. Here, the souls of the envious compensate for their lives on earth, which were partially, but not irredeemably, marred by their frustrated desire for the possessions of others.

AidaReflecting on Ai-Da’s works, the Humanities Cultural Programme will support a consideration of the role of AI in the Humanities today, and likewise the role and meaning of Dante’s Comedy itself in the modern world.A second artwork by Ai-Da reflects on a central theme of the entire vision of the Comedy, which is that knowledge and understanding are never merely intellectual abstractions, but are always embodied.

Dante, the pilgrim and protagonist of the narrative, gains in wisdom through relationships with Virgil, Beatrice, and many others encountered in the journey. The connections are made fruitful by his engagement with their faces, their expressions and their eyes.

The normal mode of existence of AI is as an unimaginably vast mass of data existing as a disembodied abstraction. However, in the embodied form of Ai-Da, it manifests itself as a humanoid robot artist.

Ai-Da’s purpose in the exhibition is to challenge the viewer, even as Dante was challenged by some of the spirits encountered in the Comedy, to think about the part which relationships with other people play in our own capacity to understand our role in the world. Finally, during a performance scheduled within the programme of the exhibition, Ai-Da will present poetry of her own creation in response to the poetry of Dante.

Ai-Da (as she made clear in her conversation with Alan Yentob) makes no false claims to human capacities which she does not share with us. But she does have the ability to push us to ask ourselves what those capacities might be.

The Dante and the Invention of Celebrity exhibition, curated by Professor Gervase Rosser, runs from 17 September 2021 to 9 January 2022 in Gallery 8, on the Lower-Ground Floor of the Ashmolean Museum.

The exhibition explores Dante’s influence on art and culture from his own time right up to the present. It includes works by William Blake, Dante Gabriel Rossetti, Salvador Dali and Tom Phillips RA; and new work by the world’s first AI artist, Ai-Da. It coincides with a display at the Bodleian Library of precious editions of Dante’s most famous work.
