The Powerful Song of Amairgen mac Miled of Brigantia (Espaiñ) in the light of Irish, Galician, Welsh and Breton Mithology

The medieval manuscript Lebor Gábala Erénn (The Book of Invasions of Ireland) is the subject of heated debate in academia regarding the possible historical veracity of parts of its possibly pre-Christian text that have not been impacted with additions from Roman and Christian history. John Carey, one of the most renowned experts on this subject, discusses in his article Donn, Amairgen, Íth and the Prehistory of Irish Pseudohistory1 the various aspects of this debate and his goal of linking the druid Amairgen and his brother Donn with Indo-European deities. In this article, I will not enter into this debate but rather offer an interpretation of the Song of Amairgen recited by Amairgen Mac Míled in the light of Irish, Breton, Welsh and Galician legends and traditions.
