Frequently Asked Questions

What is the Tuatha Dé Danann?

The Tuatha Dé Danann ("Peoples of the Goddess Danu") are the supernatural race of gods in Irish mythology. They arrived in Ireland shrouded in dark clouds and brought Four Treasures: the Sword of Light of Nuada, the Spear of Lugh that never missed, the Cauldron of the Dagda that provided endless food, and the Stone of Fál (Lia Fáil) that screamed when the rightful king stood upon it at the Hill of Tara. After being displaced by the Milesians, they retreated underground into fairy mounds (sídhe), becoming the Aos Sí — the fairy folk of later Irish legend.

Who was Cú Chulainn?

Cú Chulainn is the greatest warrior of the Ulster Cycle in Irish mythology. Born as Sétanta, he killed the fierce guard dog of the smith Culann as a boy and took its place, earning the name Cú Chulainn — "Hound of Culann." He was famous for his ríastrad (warp spasm), a terrifying battle frenzy in which his body contorted grotesquely. He single-handedly defended Ulster against Queen Medb's armies in the Táin Bó Cúailnge (Cattle Raid of Cooley), killed his friend Ferdia and his own son Connla unknowingly, and died tied to a standing stone so he would face his enemies on his feet — with the Morrígan's crow landing on his shoulder to signal his death.

Is Samhain really the origin of Halloween?

Yes — Samhain (October 31st) was the Celtic new year and marked the boundary between the world of the living and the dead. The Celts lit bonfires and wore costumes to confuse spirits that crossed over. They carved faces into turnips (not pumpkins — that came later in America) to ward off evil. When Irish immigrants brought these traditions to America, they evolved into the modern Halloween we know today.
