Walter Burley's De Motu Animalium has never appeared in print. Our edition of this work was prepared from six manuscript copies: Erfurt SB Amploniana Q. 312 (XIV century) fols. 78r–81r; London Lambeth Palace 70 (XIV) fols. 144r–147v; Lambeth Palace 74 (A.D. 1390) fols. 30r–32v; Oxford Magdalen College 80 (XIV) fols. 177v–180v; Oriel College 12 (XV) fols. 115–119; Vaticana Vat. lat. 2151 (XIV) fols. 239r–244r. The Magdalen (afterwards M.) manuscript is the most complete and is followed closely by Amploniana (A.), though A. is almost impossible to read by itself owing to the crabbed and scratchy manner in which it was written. Oriel (0.) makes the most omissions; it is incomplete and anonymous. The two Lambeth Palace MSS follow each other closely. L. 70 is anonymous and L. 74 is incomplete. Vatican was the original manuscript upon which our edition was based. It is an excellently preserved text but not quite sufficient by itself to constitute a safe reading of Burley's work. Our edition can claim to be critical to the extent that six manuscripts were consulted.
