Definition

Aeacus (Αἰακός, ὁ) is a pivotal figure in Greek mythology, renowned for his exceptional piety and justice. As the son of Zeus and Aegina, he was born on the eponymous island, where he reigned as king. His rule was characterized by wisdom and good governance, establishing him as a model sovereign.

One of the most famous stories associated with Aeacus is his plea to Zeus to repopulate Aegina when it was devastated by a terrible plague. Zeus responded by transforming the ants of his sacred tree into humans, the famous Myrmidons, who became Aeacus's people and later the warriors of his grandson, Achilles.

Aeacus's reputation as a just judge extended beyond his lifetime. Due to his unparalleled integrity while alive, he was appointed by the gods as one of the three judges of souls in Hades, alongside the brothers Minos and Rhadamanthus. His presence in the tribunal of the dead underscores the eternal recognition of his justice, making him a symbol of divine judgment.
