In his Paraphrase of On the Heavens Themistius refers to Aristotle’s De animalibus (CAG V/4: Hebr. 61,13 and 62,16) and De motu animalium (CAG V/4: Hebr. 65,3);
The source of these passages is unclear. A Paraphrase of Aristotle’s zoological writings attributed to Themistius, lost in Greek, has come down to us in Arabic (Badawl 1971). This attribution is challenged (Zimmerman and Brown 1973:323-324; Mattock 1976).
Themistius’ Paraphrase of Aristotle’s De sensu is lost in Greek; this work is mentioned by Themistius himself in his Paraphrase of On the Soul (CAG V/3: 70,8 and 77,26-27). He refers to Aristotle’s De sensu in his Paraphrase of On the Heavens (CAG V/4: Hebr. 74,9); the source of these passages has not been enquired yet. The existence of this Paraphrase by Themistius is disputed by some scholars.
Poetics
A Paraphrase of Aristotle’s Poetics, lost in Greek, is mentioned in the bio-bibliographical sources (K. al-Fihrist, Fliigel: 250,5; Ibn al-QiftI 38); it has been argued that the notice of the Fihrist seems to be confirmed by FarabI (Arberry 1937). The existence of this Paraphrase by Themistius is still challenged by some scholars (Todd 2003).
Ethics
The bio-bibliographical sources (K. al-Fihrist, Flugel: 252,3; Ibn al-Qiftl 42) credit Themistius with a Paraphrase of Aristotle’s Nicomachean Ethics. An Arabic translation is also mentioned, which is now lost. This attribution is challenged (Walzer 1963; Ghorab 1972).
