In Irish mythologyIuchar was one of the sons of Tuireann, of the Tuatha Dé Danann, and Danand. He and his two brothers Brian and Iucharba murdered Cian, the father of Lugh, one of the greatest of the Tuatha Dé Danann. They also dismembered his body and tried to cover up their crime. In recompense, Lugh made them quest all around the known world as far as Persia fetching magical weapons, which Lugh planned to use at the Second Battle of Magh Tuiredh. They succeeded in obtaining all that Lugh demanded, but returned to Ireland desperately injured, pleading for Lugh to heal them; but the latter refuses. In at least one version of this tale, Brian is the clever and subtle one, while his brothers Iuchar and Iucharba are bumbling and easily overawed by Brian. This tale of the Sons of Tuireann has sometimes been likened to an IrishArgonautica.
