What is "amyclas"

In Greek mythology, Amyclas (; ) refers to two individuals:

• Amyclas of Sparta was a mythical king of Sparta.
• Amyclas was the son of Amphion. He perished with his brothers and sisters in the massacre of Niobids. In other versions, however, he was presented as the only surviving male (with his sister Chloris). When Laius the rightful king of Thebes returned, he was exiled and fled to Sparta, where some say he founded Amyclae.
