Until recently, only two sources of Flos vernalis were known: fragments of a vocal version in binding strips in All Souls College, Oxford (MS 56); and its ornamented intabulation in the so-called Robertsbridge MS.
Two more concordances of the vocal version have meanwhile been discovered, by Cristina Alís Raurich in Karlsruhe, and in binding strips in Koblenz discovered by Karl Kügle.
The new findings allow a reconstruction of almost the entire piece, together with evidence of an otherwise absent third voice. They permit an analysis of the diminution, ornamentation and adaptation techniques in the intabulation which can be related to theoretical texts of the 14th century; Flos vernalis was more abundantly embellished than the other intabulations in Robertsbridge. Several of the sources have Cistercian connections.
This long-running series of seminars, convened by Dr Margaret Bent, considers all aspects of medieval and renaissance music. It usually consists of a talk by an invited speaker and then a period of questions, to which all attendees are encouraged to contribute.
