For centuries, none of these stories were written down at all, passed instead from one generation to the next around the fire as the nights drew in. With Halloween approaching and Samhain’s old associations stirring again, here are seven Irish myths worth retelling at bedtime, from the banshee who warns certain families of a coming death to Oisín, who followed Niamh to the land of the young and never aged a day.

Irish folklore, legends, and myths are loved across the world for the imagination and significance they bring us closer to ancient times. For many years, Irish storytelling was always oral and never written down. Instead, the stories were passed down from generation to generation.

Such is the influence that ancient Irish myths have had on our culture that many of the most popular Irish names today are taken from the characters of Irish legends, such as the heroic Fionn Mac Cumhail. 

Here are our favorite Irish legends and myths that will let you in on another side of Irish history and culture:

Finn MacCool (Fionn Mac Cumhaill)

Finn MacCool accidentally gained all the knowledge in the world. He earned an understanding of the past, present, and future because of the magical salmon he ate from the River Boyne.

The Children of Lir

The Children of Lir follows four siblings, three boys and one girl. Their mother died, but their father, Lir, quickly remarried Aoife, a woman filled with jealousy over the kids, and began to plot their murder.

Oisín of Tír na n-Óg

Oisín, who was a warrior with the Fianna, one day met Niamh Cinn Óir. She invited him to her home, which was under the waters of the lake, in a place called Tír na n-Óg (the land of the young).

Fairies

Rooted in Celtic folklore, fairies are the most magical and mystical of myths. One of the most fascinating things about Irish fairies is that they can take any form, but most often appear as humans.

Cú Chulainn

Cú Chulainn was born as Setanta, the son of human parents, but he was renamed Cú Chulainn (meaning "The Hound of Culann") after killing Culann's own dog with nothing but a sliotar and hurl. He went on to work for Culann to pay him back for killing his hound, and the Irish hero battled many monsters and heroes for his boss.

The Banshee

The bean-sidhe (evolved into Bean Sí, literally meaning "fairy woman," and then anglicized to Banshee) is a fairy who may have been an ancestral spirit appointed to warn members of certain ancient Irish families of their time of death. She appears in one of three guises: a young woman, a stately matron, or a ragged old hag.

The Legend of Diarmuid & Grainne

Labeled as the great romantic legend of Ireland, the story follows the love triangle between the warrior Fionn mac Cumhaill, the princess Gráinne, and Diarmuid Ua Duibhne.
