After his older brother died without issue, Lamedon was to succeed him, but the kingdom was seized by
Epopeus. However, Epopeus died of a wound he had received in the battle against
Nycteus, who attacked Sicyon in order to retrieve and punish his daughter
Antiope, who had fled and married Epopeus. Lamedon then took over as his heir; according to
Pausanias, after Nycteus' death in the fight his brother
Lycus returned to continue the war, but Lamedon chose to avoid any more bloodshed, and instead gave up Antiope to him. Later, when Lamedon was engaged in a military conflict against
Archander and
Architeles (sons of
Achaeus and the husbands of the
Danaïdes Scaea and
Automate), he had
Sicyon of
Attica for an ally. In reward for Sicyon's assistance, Lamedon gave him Zeuxippe to wife and pronounced him his successor. ==Notes==
