τῶν ἐν νόμῳ δὲ και προφήταις ᾽Εβραϊκῶν ὀνομ€των αἱ ἑρμηνεῖαι. The way in which Eusebius speaks of this work (τοῦ αὐτοῦ σπουδαῖ εἰναι λέγονται) shows that it lay before him as an anonymous work, which, however, was “said to be the result of Philo’s industry.” Jerome, too, in speaking of the same work (at the beginning of his own work, De nominibus Hebraicis), says that, according to the testimony of Origen, it was the work of Philo. For Jerome, too, therefore, it was an anonymous work. This testimony of Origen cannot, according to Schürer, be found in his extant works, but in his Comment. in Joann. II. 27 (ed. Lommatzsch, I. 50) he speaks of a work upon the same subject, the author of which he does not know. The book therefore in view of the existing state of the tradition in regard to it, is usually thought to be the work of some other writer than Philo. In its original form it is no longer extant (and in the absence of this original it is impossible to decide the question of authorship), though there exist a number of works upon the same subject which are probably based upon this lost original. Jerome, e.g., informs us that his Liber de Nominibus Hebraicis (Migne, III. 771) is a revision of it. See Schürer, p. 865 sq.
