Mythology
Celtic mythology
The Celts lived across much of Europe, but their stories have reached us mainly from Ireland, Wales and Scotland, written down by monks in the Middle Ages. They tell of a divine people, the Tuatha Dé Danann, of heroes such as Cú Chulainn and Finn McCool, of fairy hills where time flows differently and of creatures of the water. Britain also gave us the legends of King Arthur, which spread all over Europe, Italy included.
Who they were, where, and how we know
The Celts were Iron Age peoples who from the 1st millennium BC spread across much of Europe, from Spain to Turkey. In the end they survived on the islands: Ireland, Wales, Scotland, Brittany. Among them were the druids, priests and sages, who according to ancient authors did not write their knowledge down.
That is why almost everything we know comes from Christian monks of the Middle Ages, who in Ireland and Wales wrote down the old stories, for example in the «Book of Invasions of Ireland» or in the «Mabinogion» (kept in 14th-century manuscripts). They are genuine tales, but they passed through a Christian pen: much is reconstruction and scholars still debate it.
At the centre are the Túatha Dé Danann, the «people of the goddess Danu»: the Dagda, the goddess Brigid, the shining Lugh, the Morrígan. Then heroes such as Cú Chulainn, and an Otherworld of sídhe and fairies under the hills.

Ciro Simone Irmici
I build websites, apps and games. I built the Atlas with artificial intelligence and I check every card and every source myself. I am not a scholar of mythology: I tell these legends with respect and always say where they come from. If you know a legend from your town, write to me.
