It is suggested that the word 'boccanelle' in the colophon may be a latinized version meaning 'of Boken Hall'. This was a Hall near Lincoln College, Oxford, and is referred to in Wood's City of Oxford, edited by A. Clark, 1890, Vol. II, p. 82. According to Emden in his Biographical Register of the University of Oxford to A.D. 1500, Vol. II, this work was originally written in 1335. It was first printed at Pavia in 1481 (B.M.C. VII, 997].
