This is the third volume in the series of commentaries on Early Greek Epic Fragments ( EGEF III). It contains introduction, text, translation, and commentary on the Herakleia by Panyassis of Halikarnassos and on the Theseis . Two other volumes have been already published ( EGEF I: Genealogical and Antiquarian Epic , De Gruyter 2017; EGEF II: Epics on Herakles: Kreophylos and Peisandros , De Gruyter 2022) and one more is to follow ( EGEF IV: The Persika by Choerilos of Samos ). This sub-series within TCSV aims to provide scholars and students with up-to-date commentaries on the extant fragments of early Greek epic that have not received, contrary to Cyclic epic, the attention they deserve.
