Fomorian Ancestor Figure
Bolg is a Fomorian figure whose name is the same word as the “Bolg” in Fir Bolg — the “bag people” or “lightning people,” one of the earliest mythological peoples to settle Ireland. Whether that shared name is a coincidence or a deliberate connection is one of Irish mythology’s more interesting open questions.
The name Bolg may mean “bag” or “belly,” or it may connect to an older root meaning “lightning” or “to strike” — the same root that underlies the Belgae of Gaul and Britain. A Fomorian named Bolg, appearing at the boundary between the Fomorian tradition and the Fir Bolg people, suggests that the two groups shared something deep in the older layers of the mythology, even if the later accounts treat them as entirely separate.
He has no individual story. He is preserved in genealogical records and battle-lists, his significance carried in his name rather than his deeds.
