I want to know the answer to the following question:
Who taught Antigonus II?
All the background I'm provided with is that "Antigonus II, a student of Zeno of Citium, spent most of his rule defending Macedon against Epirus and cementing Macedonian power in Greece, first against the Athenians in the Chremonidean War, and then against the Achaean League of Aratus of Sicyon.". Is that enough to answer the question?
