 The stress on Plato's Pythagoreanism on the part of Pythagoreans revives and extends connections between Plato's metaphysics and Pythagorean ideas noted already by Plato's younger associates. Already Aristotle saw these connections (e.g. Metaphysics A.6, M.3, N.3). That early Academics like Xenocrates showed strong interest in Pythagoras' doctrines is presumably because they took them to be present in, or close to, Plato’s. They even wrote treatises on them (e.g. Diogenes Laertius IV.13). We hear that Plato was accused of having copied the Timaeus from Philolaus' book (Diogenes Laertius VIII.85) and in the 3rd c. BCE Timon of Phlius parodied Plato for this (Aulus Gellius, Noctes Atticae III.17.4). The renewed emphasis on the Timaeus in the work of Platonists of the first centuries CE, which we can attribute already to Eudorus (see Dillon 1977, 117–121), is closely associated with the revival of Pythagorean Platonism. Platonists considered the Timaeus to communicate Pythagorean doctrine and even argued that it was inspired by the work of “Timaeus Locrus”, a late forgery in pseudo-Doric dialect (cf. Proclus, In Timaeum I.7.17-8.29).  Numenius is following ample precedent in assigning a central role to the Timaeus for deriving a system of first principles on the basis of Plato's metaphysics (Baltes 1975, 241–242). His interest in numbers (he wrote a work on numbers), to which he assigns an ontological role (fr. 2.20-24) may well be for him another Pythagorean doctrine that Plato had taken over (see Staab 2002, 99–100).
