Quetif and Echard, in order to maintain the cooperation supposed to exist between William and Aquinas, also hold that William’s translation of the Elementatio theologica of Proclus made at Viterbo in 1268 was from the Arabic and not from the Greek, since Aquinas says in his commentary on that work that the Greek text had not yet been found. This conclusion is also drawn by HL XXI, 148.
[1980] See Duhem II (1914), 394, for a like opinion expressed by Augustine.

[1982] Chartularium univ. Paris. (1889-1891), I, 504-5, dated May 2, 1274, “... humiliter supplicamus ut cum quaedam scripta ad phylosophiam spectantia, Parisius inchoata ab eo, quae in suo recessu reliquerit imperfecta, et ipsum credamus, ubi translatus fuerit, complevisse, nobis benevolentia vestra cito communicari procuret, et specialiter super librum Simplicii, super librum de celo et mundo; et expositionem Tymei Platonis, ac librum de aquarum conductibus et ingeniis erigendis; de quibus nobis mittendis speciali promissione fecerat mentionem.”
[1983] Of this commentary the third and fourth books were finished by Peter of Auvergne.
[1984] Aquinas is even credited with an abridgement of the Almagest in CLM 56, 1436 A. D., “Almagesti abbreviatum per magistrum Thomam de Aquino”; cited by Björnbo (1911), p. 129. But this, I take it, is the same as the abridgement of the Almagest which Averroes is said to have made and which was translated by the order of Alfonso the Great: see Digby 236, 14th century, fol. 190, where the writer of a prologue to another work of Averroes remarks, “Scivit enim Averoys optime Almagestum. Nam vidi per eum Almagesti abbreviatum, quem librum fecit transferri Rex Alfonsus Magnus, et habetur Bononie et in Hispania.”
