Panyassis was the son of Polyarchus (Ancient Greek: Πολύαρχος) from Halicarnassus, but the historian Duris of Samos claimed that Panyasis was the son of Diocles (Ancient Greek: Διοκλῆς) and from Samos. In addition, the historian Herodotus was either his nephew or his cousin. There was also another person of the same name, possibly the grandson of the poet, who wrote a work in two books on dreams.
The Suda encyclopedia mentions Panyassis.
Panyassis enjoyed relatively little critical appreciation during his lifetime, but was posthumously recognised as one of the greatest poets of archaic Greece. His most famous works are: the Heracleia about the hero Heracles, written in epic hexameter, and the Ionica about the histories of the Ionian cities of Asia Minor, reportedly written in pentameter. These works are preserved today only in fragments. It is believed that he also wrote other works which have since been lost.
