He lived in the third or 2nd century BC. The period of his life is doubtful :
Alfred Gercke places him in the time of
Ptolemy Lathyrus (latter part of 2nd century BC); reliable testimony indicates that he was a contemporary of
Ptolemy Philometor (middle of 2nd century BC). Aristobulus was among many philosophers of his day who argued that the essentials of Greek philosophy and metaphysics were derived from Jewish sources. Philosopher
Numenius of Apamea (2nd century AD) echoes this position in his well-known statement "What is Plato but Moses speaking Attic Greek?" (1.150.4) Aristobulus maintained, 150 years earlier than Philo, that not only the oldest Grecian poets,
Homer,
Hesiod,
Orpheus, etc., but also the most celebrated Greek thinkers, especially
Plato, had acquired most of their wisdom from Jewish sages and ancient Hebrew texts (Gfrorer i. p. 308, also ii. 111–118) (
Eusebius citing Aristobulus and Numenius Ev ix. 6, xi. 10). He was among the earliest of the Jewish
Alexandrian philosophers whose aim was to reconcile and identify Greek philosophical conceptions with the
Jewish religion. Only a few fragments of his work, apparently entitled
Commentaries on the Writings of Moses, are quoted by
Clement, Eusebius and other theological writers, but they suffice to show its object. In addition, there is extant a small passage concerning the time of the
Passover festival, quoted by Anatolius. In addition, Aristobulus is the author of the first recorded
Hexaemeron, although it has been lost. ==Incorrect or heterodox descriptions==
