Argonautica Orphica (Greek: Ὀρφέως Ἀργοναυτικά) is a Greekepic poem dating from the 5th–6th centuries CE. It is narrated in the first person in the name of Orpheus 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. Another related work is the Lithica (describing the properties and symbolism of different stones).
The narrative is basically similar to that in other versions of the story, such as the Argonautica of Apollonius Rhodius, on which it is probably based. The main differences are the emphasis on the role of Orpheus and a more mythological, less realistic technique of narration. In the Argonautica Orphica, unlike in Apollonius Rhodius, it is claimed that the Argo was the first ship ever built.
