Abstract

Contrary to what is often assumed since the seminal studies of Puech, I argue that Numenius’ interest in Oriental Wisdom is part of his Platonist stance. The most important testimony is fr. 1a des Places, which shows that Plato is not only the reference‑point but also the criterion and measure to judge the truthfulness of the other philosophical traditions and religions. Numenius’ dualism therefore can be explained as an attempt to preserve the transcendence of the first principle, the typical problem of Middle Platonists as opposed to Hellenistic philosophies such as Stoicism.
