Dr. Robert Eisler in Revue d’assriologie et d’archéologie orientale 1905, p 57; Orpheus the Fisher (London: J.M. Watkins, 1921) Plate X describes this as an Orphic Sacramental Bowl. The central figure is indeed female, but the 16 surrounding stations around her, beginning with the first station and proceeding clockwise depicts Orpheus the Fisher with his fishing pole with the line wrapped around it. He holds a mesh bag in the other hand.
The bowl is representative of a widespread and popular Orpheus-Christos Cult throughout the Greco Roman empire ( rivaling Mithraism) with unique religious, artistic, and literary influences of the West.
Joseph Campbell traces the mystic fisherman motif back to a Babylonian seal known as ‘The Warden of the Fish’ (2nd millennium B.C.E) Many believe this is evidence of the early origins of Christianity predating Jesus by centuries, where Orpheus, “The Good Shepherd and Harrower of Hell” was the model for what would become Jesus many centuries later. ( see The History of Hell, by Alice K. Turner p. 24 Harcourt Brace and Company 1993)
“A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”
