In Wales, Beli was the husband of Danu and father of the Dagda, Dian Cecht, Lir, Lugh, Gwydion, Govannnon, Arianrhod, Gilfaethwy and Amaethon.
He was worshipped on May 1 at Beltaine ("Fire of Bel"). Purifying fires were lit and cattle were forced to walk between them before being allowed to go to pasture.
Belenus was eventually worshipped by Celts in Aquitaine, Austria, Italy, Britain, Gaul, Ireland and Wales.
