< Aeacus, son of Actor >

1 Origin

In 1307 BC, Aeacus was born in Phthia of Thessaly.

Aeacus' mother was Aegina, daughter of the river god Asopus.

Aegina's father was Sicyon, son of Marathon, who lived in Sicyon of Argolis.

Many historical sources mention Aeacus' mother, Aegina, but not the name of Aeacus' father.

The only one to mention Aegina's husband is Actor.

Actor was the son of Myrmidon, and it is assumed that the legend of the ants originated in Aegina, where Aeacus lived. 

2 Family

Aeacus married Psamathe, daughter of Scyrius, and had a son, Phocus.

Aeacus then married Endeis, daughter of Sciron, and had two sons, Peleus and Telamon.

Phocus migrated from Aegina to the northwest of Phocis, near Naubolenses (later Drymaea).

Peleus emigrated from Aegina to Eurytion, son of Actor, who lived in Phthia.

Eurytion was the brother of Aeacus, father of Peleus.

Telamon emigrated from Aegina to Salamis and married Glauce, daughter of Cychreus.

3 Others

3.1 Emigration to Aegina

Aeacus founded Dia in Thessaly, and then moved to the island of Oenoe, near Sicyon where his mother was born. 

The island came to be called Aegina after Aeacus' mother.

3.2 Arbitration of the Succession Issue

Aeacus mediated a dispute between Pandion's son Nisus and Pandion's son-in-law Sciron over the succession of Megara. 

Aeacus' wife's father Scyrius (or Sciron, Chiron, Scirus) was the biological father of Pandion's adopted son Aegeus. 

In other words, Aeacus and Aegeus were sworn brothers, and through Aegeus, Aeacus was also sworn brother to Nisus and Sciron. It seems likely that Aegeus, who was king of Athenians at the time, had Aeacus, who was known for his piety, mediate the dispute between the sworn brothers.

3.3 Aeacus's whereabouts

The whereabouts of Aeacus after his sons left Aegina are unknown.

It is assumed that Aeacus' sons left the island because the victorious Cretans immigrated to Aegina after the battle between Minos and Megara.

Aeacus' family lived together with the Cretans, but it is believed that they left the island after Aeacus' death.
