Fiachu Muillethan(broad crown) orFiachu Fer Da Liach(of the two sorrows), son ofÉogan Mór,was a legendary king belonging to theDeirgtine,the proto-historical ancestors of theEóganachtadynasties ofMunster.He is known primarily from the sagaForbhais Droma Dámhgháire,in which he is assisted by the famousMug Ruith,who repels an invasion of his kingdom byCormac mac Airt.The sons of Fiachu Muillethan were Ailill Flann Mór andAilill Flann Bec.
Like his father Éogan Mór, grandfatherAilill Aulom,and great-grandfatherMug Nuadat,Fiachu Muillethan appears to be mainly fictional. The circumstances of his life are entirely legendary, seemingly invented so as to provide the Eóganachta with an ancestral contemporary of Cormac mac Airt. This is apparent from the conception of Fiachu as described in theCath Maige Mucrama.
While the career of Fiachu Muillethan may be entirely legendary, that of his supposed great-grandsonConall Corc,the true founder of the Eóganachta, may preserve an amount of historical fact.
As in many such cases,MuillethanandFer Da Liachmay have started out two different figures later thought to be the same, whether mythological or historical. The medieval genealogists are at pains to assert they were identical but base their argument only on the story of Fiachu's birth in theCath Maige Mucrama,a well known saga ofpolitical fiction.
