c. 480–400 BCE
Greek Religious Practice
Eros on the Battlefield — The Living Cult
While philosophers argued about Eros in symposia, soldiers invoked him before battle. Both the Spartans and the Cretans are documented as offering sacrifice to Eros before going into combat — not to be spared from death, but because they understood Eros as the force that held the battle line together. The reason given was precise: safety and victory depend on the bond between men who stand side by side. Eros was the name for that bond.
The city most devoted to Eros, Thespiae in Boeotia, kept the oldest Eros cult in Greece — a stone so ancient it had no human form, only the raw presence of the god. In 480 BCE, when the Spartans sent 300 men to hold the pass at Thermopylae against the Persian army, the Thespians sent 700. All 700 died. The city that worshipped Eros above all others was the one that walked most completely into death for others. A monument to them, featuring a bronze statue of Eros, now stands at the site. Meanwhile, coins minted at the hilltop temple of Aphrodite Erycina in Sicily in the late 5th century BCE depict Aphrodite seated alongside Eros — the love goddess and the erotic force together, stamped in official sacred currency. Eros was not only a philosophical concept in this period. He was a living religious practice with a cult center, a festival, documented sacrifices, and a battle record.
