Alcathous (son of Pelops)

Alcathous was a figure in Greek mythology, known primarily as one of the sons of Pelops and Hippodamia. He is associated with the founding and fortification of Megara.

According to tradition, Alcathous left Elis after accidentally killing his brother or, in some versions, being implicated in a conflict related to his father's kingdom. He traveled to Megara, which at the time was under the rule of King Megareus, a son of Poseidon or Onchestus.

Alcathous aided Megareus in driving away a Cithaeronian lion that was plaguing the land. In gratitude, Megareus offered Alcathous his daughter, Pyrgo (or Evaechme in some accounts), in marriage and designated him as his heir.

Upon Megareus' death, Alcathous succeeded him as king of Megara. He is credited with rebuilding the city walls, which had been destroyed by the Cretans under Minos. As a token of gratitude for his work on the walls, Apollo (or Poseidon in some versions) is said to have helped him by placing his lyre on a stone, which then moved into place on its own.

Alcathous and Pyrgo had several children, including Ischepolis, Callipolis, Iphinoe, and possibly others depending on the source.

The heroic status of Alcathous is further cemented by the sanctuary dedicated to him in Megara, indicating the veneration he received as a founder and protector of the city. His story highlights themes of exile, redemption, and the establishment of order in the mythological landscape of ancient Greece.
