The Cult
Olympus was worshipped at its foot and on its shoulder, never on its crown. The sanctuary city of Díon — excavated from 1928 — was the working base of Zeus Olympios: processions, games, and royal sacrifice, and Plato's Gorgias already mentions the games Archelaus staged there. Macedonian kings made it their ritual stage, Philip and Alexander celebrating victories at Díon before campaigning. High on the massif, the open-air sanctuary on the Agios Antonios plateau — just below the summits, at the edge of the measurable world — received votives carried above the treeline, the closest any ancient came to the cloud-hidden palace; no temple crowns the peak itself, which was left to the gods. Across Greece the cult followed the name: the Twelve Olympians shared their great altar in the Athenian agora from 522 BCE, and Zeus Olympios became the honorific by which cities elevated the sky-father. Olympus needed no temple on high; every Olympian cult was its temple.
