Lia Fáil

The Lia Fáil (Irish pronunciation: [ˌl̠ʲiə ˈfɑːl̠ʲ], meaning Stone of Destiny) is a stone at the Inauguration Mound (Irish: an Forrad) on the Hill of Tara in County Meath, Ireland, which served as the coronation stone for the High Kings of Ireland. It is also known as the Coronation Stone of Tara. In legend, all of the kings of Ireland were crowned on the stone up to Muirchertach mac Ercae c. AD 500.

There are several different, and conflicting, legends in Irish mythology describing how the Lia Fáil is said to have been brought to Ireland. The Lebor Gabala, dating to the eleventh century, states that it was brought in antiquity by the semi-divine race known as the Tuatha Dé Danann. The Tuatha Dé Danann had travelled to the "Northern Isles" where they learned many skills and magic in its four cities Falias, Gorias, Murias and Findias. From there they travelled to Ireland bringing with them a treasure from each city – the four legendary treasures of Ireland. From Falias came the Lia Fáil. The other three treasures are the Claíomh Solais or Sword of Light, the Sleá Bua or Spear of Lugh and the Coire Dagdae or The Dagda's Cauldron.

Some Scottish chroniclers, such as John of Fordun and Hector Boece from the thirteenth century, treat the Lia Fáil the same as the Stone of Scone in Scotland. According to this account the Lia Fáil left Tara in AD 500 when the High King of Ireland Murtagh MacEirc loaned it to his great-uncle, Fergus (later known as Fergus the Great) for the latter's coronation in Scotland. Fergus's sub-kingdom, Dalriada, had by this time expanded to include the north-east part of Ulster and parts of western Scotland. Not long after Fergus's coronation in Scotland, he and his inner circle were caught in a freak storm off the County Antrim coast in which all perished. The stone remained in Scotland which is why Murtagh MacEirc is recorded in history as the last Irish King to be crowned on it.
