In
Greek mythology,
Eurysthenes (, "widely ruling") was one of the
Heracleidae, a great-great-great-grandson of
Heracles, and a son of
Aristodemus and
Argia. His twin was
Procles. Together they received the land of
Lacedaemon after
Cresphontes,
Temenus and
Aristodemus defeated
Tisamenus, the last Achaean king of the
Peloponnesus. Eurysthenes married Lathria, daughter of
Thersander, King of Kleonoe, sister of his sister-in-law Anaxandra, and was the father of his successor,
Agis I, founder of the Agiad dynasty of the
Kings of Sparta.
