Hyperbolus

Hyperbolus (, Hyperbolos; died 412/411 BC) was an Athenian politician active during the first half of the Peloponnesian War, coming to particular prominence after the death of Cleon. In 416 or 415 BC, he was the last Athenian to be ostracised.

==Life== A fragment of a document by 4th-century BC Greek historian Theopompus suggests that Hyperbolus was the son of Chremes, but surviving ostraka prove that his father's name was actually Antiphanes. Some ancient sources claim that Hyperbolus was from a slave family, though the fact that his father had a Greek name makes this unlikely.
