6. Indo-European Equivalent: None. Note that the common Neopagan identification of Oghma and Ogmios with the Vedic Fire God Agni has no scholarly support of which I am aware.

8. Iconography: The Roman poet describes Hercules depicted in Gaul with his Classical lion skin and club, but as an old man drawing behind him a band of men attached to him by thin, gold chains linking their ears with his tongue.4
9. Significance: Ogmios is the God of Eloquence, but also of strength, a deity patronizing both intellectual and physical pursuits. He is, however, a deity often invoked in Gallo-Roman cursing tablets, which make clear that He was a servant of the Chthonic Gods, with a dark and dangerous aspect.5
Lucian of Samosata, after seeing an image of Ogmios in Gallia Narbonensis, compared him to Heracles with the classic attributes of a a psychopomp. One of the lead curse tablets from Bregenz links him to Dis Pater; the other the god of death and the underworld.
