ABSTRACT
The Old Hall Manuscript, known since its acquisition by the British Library in 1973 as Additional MS. 57950, contains on fols. 22v–23 a Gloria by Pycard (fig. 1a,b) which is a rare and early example of double canon, published as no. 27 in the edition. 1 Its only clear antecedent in that respect is the—likewise English—‘sumer’ canon in B L, Harley MS. 978, technically a very different piece, involving that special form of canon we know as round, over a simple two-voice rondellus ostinato. 2
