² Even in the early fourteenth century we find the story that William of Moerbeke translated all Aristotle's works of moral and natural philosophy; recent scholars have supposed that he profiled by direct consultation with William about obscure points of the translation. The editors of the Ethica and of the Politica in the Leonine edition of the Opera omnia have, however, shown that the story of the collaboration between Thomas and William is not supported by the evidence and further that Thomas does not seem to have been particularly interested in making use of the most recent translation, but often cites older ones, even those made from the Arabic, rather than the latest version from the Greek. See Aquinas, Thomas, Opera omnia (Rome 1882 ff.) XLVII 1 (Sententia libri Ethicorum) ^*232–34^*; ibid. XLVIII (Sententia libri Politicorum) A 63, note 1.

³ Sixtus Medices, in the preface to the 1530 edition of the commentary on the De generatione (§57) writes: ‘… illudque iam per scholas vulgatissimum dictetur adagium, Ubi tacuerit Thomas, Aristotelem mutum fuisse.’ The statements of Nifo are found in Grabmann, ‘Die Aristoteleskommentare…,’ 310–11. Grabmann, also cites a remark of Pico comparable to the adage of Sixtus Medices: ‘Sine Thoma mutus esset Aristoteles…’ (p. 312).Google Scholar

¹⁶ For examples, see the following manuscripts listed in the Sententia libri Ethicorum1^*f.: Google Scholar

No. 16. Cambridge, Peterhouse 208. Here the lemmata of the Grosseteste translation have been omitted; in their place we find the entire translation of Bruni.

No. 34. London, British Museum, Royal 9.E.1. The same procedure is followed as in the above manuscript, and it appears that the two manuscripts were produced in the same scriptorium.

¹⁷ For examples, see the following manuscripts listed ibid.: Google Scholar

No. 79. Città del Vaticano, Biblioteca Apostolica, Vat. lat. 3003. The manuscript contains the Ethica translated by Bruni; a second hand of the late fifteenth century has added selections from the Thomas commentary, though often omitting his ‘divisions’ since these do not correspond to the Bruni translation.

No. 92. Cambridge, University Library, Hh.I.6 (1620). The commentary of Thomas has been added in the margins of the Bruni translation; the lemmata of the Grosseteste translation have been replaced by those of Bruni.

No. 93. El Escorial, Real Biblioteca del Monasterio de San Lorenzo, f.II.3. The manuscript contains the Bruni translation. In the margins there is a commentary consisting of excerpts mainly from Albertus de Saxonia but also from Thomas and other writers. It is noteworthy that these excerpts have been ‘revised’ so as to correspond to the text of the Bruni translation: ‘liber… commentario instructus est, e plurium scriptorum commentariis excerpto, quorum tamen verba verbis Libri Ethicorum a Leonardo Aretino translati accommodata sunt.’

No. 120. Città del Vaticano, Biblioteca Apostolica, Chigi E. VII.224, and No. 121 Ottob. lat. 1526. In both cases the Liber Ethicorum in the Bruni translation is accompanied by excerpts from the commentary of Thomas.

I know of only one case among the manuscripts of the Thomas Politica commentary where something similar occurs. See the Sententia libri Politicorum A 14:

Firenze, Biblioteca Medicea Laurenziana, Gadd. Plut. XC sup. 86. Here we find the Prologue of Thomas, and Book I of the Politica in the Bruni translation, with glosses taken from the Thomas commentary.
