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
Branwen ferch Llŷr is the deeply moving Brittonic mythological sovereign of noble love, diplomatic reconciliation, and tragic compassion, serving as the central protagonist of the Second Branch of the Mabinogi (Branwen ferch Llŷr). Celebrated in the Welsh Triads as one of the Three Paramount Sovereign Matrons of Britain, Branwen was offered in dynastic marriage to King Matholwch of Ireland to establish an enduring peace between the two island realms. However, her malicious maternal half-brother Efnisien, enraged at not being consulted in the marital negotiations, brutally mutilated the Irish delegation's horses in the royal stables. To atone for the horrific insult, the giant sovereign Brân the Blessed (Bendigeidfran) compensated Matholwch with the magical Cauldron of Rebirth (Pair Dadeni). Upon arriving in Ireland, Branwen bore a royal son named Gwern; yet simmering resentment over the horse outrage erupted among the Irish chieftains, who compelled Matholwch to banish his queen from the royal chamber and condemn her to the palace kitchen, where she was forced to bake bread and endured a daily blow to the ears from the court butcher. In her sorrowful captivity, Branwen reared a starling in the kneading trough, taught it to speak, and bound to its wing a letter detailing her plight, sending the bird across the Irish Sea to her brother Brân. The subsequent rescue expedition led to a catastrophic war between both nations; following the horrific murder of young Gwern, who was seized and thrown into the hall fire by Efnisien, both realms were left utterly devastated. Rescued by the seven surviving British warriors, Branwen landed at Aber Alaw in Anglesey, looked back across the waters toward Ireland and Britain, and broke her heart in pure grief that two fair islands had been destroyed on her account, dying upon the riverbank.
