The Orphic Argonautica or Argonautica Orphica is a Greek epic poem dating from the 4th century CE. It is narrated in the first person in the name of Orpheus, one of the Argonauts, and tells the story of Jason and the Argonauts. It is not known who the real author is. The poem is found in manuscripts either on its own or together with the Orphic Hymns and other hymns such as the Homeric Hymns and those of Proclus and Callimachus. The poem was lost, but in the fifteenth century it was found and copied in a manuscript by the Neoplatonic Greek scholar Constantine Lascaris, who is considered a Pythagorean Orpheus.
