Ichor
The ethereal fluid that flowed through the veins of the Greek gods in place of mortal blood.
The Meaning of Ichor
When Diomedes wounded Aphrodite on the battlefield at Troy, Homer tells us that what flowed from her was not blood but ichor — the immortal substance that coursed through divine veins. It was golden or translucent, and its presence in a body was the physical marker that separated god from mortal. The gods did not eat bread or drink wine, Homer explains, and so they had no blood. Instead, their diet of ambrosia and nectar produced ichor, the fluid of deathlessness. When Athena guided Diomedes' spear into Ares' belly, ichor again poured out, and the war god screamed as loud as ten thousand men, but he could not die. The concept carried theological weight — the gods were not merely powerful humans but beings of a different substance entirely. Their bodies healed instantly, their ichor clotting without scar. Later Greek medical writers borrowed the term. Hippocratic texts use ichor to describe the thin, watery discharge from wounds, a deliberate echo suggesting that mortal flesh produces only a pale imitation of divine fluid.
