 Numenius' influence goes beyond the contemporaries of Plotinus. Iamblichus, Proclus, Syrianus, Philoponus and Damascius also draw on his work, although not always with approval (see frs. 46a-51). Numenius was also used by Calcidius in his commentary on the Timaeus (297.7–301.20 Waszink; fr. 52; see Phillips 2003) and by Macrobius in his In Somnium Scipionis (frs. 54–55), a work that exerted considerable influence in the Middle Ages.
