Panyassis of Halicarnassus, sometimes known as
Panyasis , was a 5th-century BC
Greek epic poet, famous for the
Heracleia and the
Ionica. It is believed that he also wrote other works which have since been lost. He was critically unappreciated during his lifetime, but was posthumously recognised as one of the greatest poets of
archaic Greece. He was either
Herodotus' uncle or cousin. In 454 BC, Panyassis was executed for political activities by the tyrant of Halicarnassus and grandson of
Artemisia, Lygdamis ΙΙ , after an unsuccessful uprising against him.
