Ogmios

Ogmios (also known as Ogmius; Ancient Greek: Ὄγμιος; Latin: Ogmius, Ogimius) was the Celtic deity of eloquence. He is described as resembling a more elderly version of Heracles, and uses his powers of persuasion to bind men to himself, with stories describing thin, long chains connecting his tongue to the ears of his followers.

Most of the knowledge about Ogmios comes from comparisons between him and powerful deities and heroes in other ancient cultures.
