10 Euros Aristotle

Issued as part of Greece's long-running ancient philosophers commemorative program, this coin marks the 2,400th anniversary of Aristotle's birth in 384 BC. Born in Stagira in the Chalcidice peninsula, Aristotle spent two decades at Plato's Academy before Philip II of Macedon appointed him tutor to the young Alexander — a relationship that would prove consequential for the entire Hellenistic world.
