What is "eurysaces"

Eurysaces in Greek mythology was the son of the Ajax and the former-princess captive-slave girl Tecmessa. He was venerated in Athens. Eurysaces was named after his father's famous shield. In Sophocles' tragedy Ajax, the protagonist hands the shield to his young son before committing suicide. Eurysace was then taken to Ajax’s native land, Salamis Island, and he soon became king there. Eurysaces’s uncle Teucer, founded the town of Salamis on Cyprus, and later attempted to returned to the island, but he was repelled by Erysaces. Teucer later established Galacia in Spain. Sophocles wrote a play titled Eurysaces, but only one quotation from it survives.
