Lugus

Lugus was a deity apparently worshipped widely in antiquity in the Celtic-speaking world. His name is rarely directly attested in inscriptions, but his importance can be inferred from placenames and ethnonyms, and his nature and attributes are deduced from the distinctive iconography of Gallo-Roman inscriptions to Mercury, who is widely believed to have been identified with Lugus, and from the quasi-mythological narratives involving his linguistic descendants, Irish Lugh and Welsh Lleu Llaw Gyffes.
