The Celtic gods were worshipped by the peoples of Ireland, Britain, and Gaul, with the aid of the druids, their priestly caste. They venerated them in sacred groves, springs, and wells, without great stone temples. Many of their myths survived in the Irish and Welsh sagas, recorded by medieval monks.
The Celtic wheel of the year turned on four great fire festivals: Samhain, the origin of Halloween, opened winter and contact with the dead; Imbolc, Beltane, and Lughnasadh marked spring, summer, and the harvest. The druids led the rites in sacred groves called nemeton.

At a glance
Lugh Lámhfhada (Lugh of the Long Arm), also glorified as Samildánach (“Master of All Arts” or “The Polytechnic”), is the radiant, invincible, wise and supreme Celtic god of spiritual sunlight, craft innovation, martial arts, rhetoric, metalworking, music, the strategic board game fidchell and rightful kingship in Irish and continental Celtic mythology (the Gallo-Roman god Lugus). Born of the prophetic union between the prince Cian of the divine Tuatha Dé Danann and the princess Ethniu, daughter of the fearsome king Balor of the Evil Eye of the Fomorians, Lugh united in his veins the blood of two rival peoples, embodying the overcoming of chaos through the perfect synthesis of creative intelligence. Presenting himself at the royal gates of Tara before King Nuada, Lugh won supreme command of the armies by showing that he possessed not one isolated skill but mastered all the professions and sciences of the universe at once (being smith, champion, harpist, poet, sorcerer, physician and goldsmith). Leading the gods at the Second Battle of Mag Tuired, Lugh fulfilled the ancestral prophecy by defeating his own grandfather Balor with a precise and devastating shot from his magical sling (Tatlum), piercing the tyrant's poisonous eye. Founder of the legendary annual festival of Lughnasadh (held on August 1 in honor of his foster mother Tailtiu), Lugh embodies the solar triumph of civilization, multidisciplinary excellence and the sovereignty that illuminates human society through knowledge, justice and technical skill. The solar master of all arts embodies the multidisciplinary excellence and practical intelligence that defeat oppression with honor, justice and unshakable cosmic wisdom. The solar king of Tara embodies the sublime union between the skill of craftsmen and the lucidity of sages, crowning Celtic history with invincible dignity and creative light. The lord of the long arm and of the spear of fire is the sublime embodiment of human competence raised to divine dignity, guiding men along the path of light and justice. His invincible spear and his luminous wisdom remain as the sacred promise of liberation for the whole Celtic people. He is the solar hero who illuminates the hearts of the just and frees peoples from oppression with nobility and truth.
