  Matters were likely more complicated still, and the state of the evidence leaves much room for interpretative disagreement. Some scholars have argued that his engagement with Platonism was more thoroughgoing than ancient and modern interpreters who have emphasized his debts to Stoicism tend to allow. The tantalizing fact that Zeno studied with the Academic scholarch, Polemo, lends some plausibility to the idea that Stoicism was itself indebted to the Old Academy in certain respects. And the case has been made that Antiochus exerted an influence on, or prefigured, developments in Middle Platonism (see Bonazzi 2012).
