ὁ ᾽Αλέξανδρος ἢ περὶ τοῦ λόγου žχειν τὰ ἄλογα ζῶα, De Alexandro et quod propriam rationem muta animalia habeant, as the title is given by Jerome (de vir. ill. c. 11). The work is extant only in Armenian, and is given by Aucher, I. p. 123–172, and in Latin by Ritter, Vol. VII. Two short Greek fragments are also found in the Florilegium of Leontius and Johannes, according to Schürer. This book is also one of the separate works of Philo, and belongs to his later writings. See Schürer, p. 860 sqq.
