Lugh's father is Cian of the Tuatha Dé Danann, and his mother is Ethniu: daughter of Balor, of the Fomorians. In "Cath Maige Tuired" their union is a dynastic marriage following an alliance between the Tuatha Dé and the Fomorians. In the "Lebor Gabála Érenn," Cian gives the boy to Tailtiu, queen of the Fir Bolg, in fosterage. In the Dindsenchas, Lugh, the foster-son of Tailtiu, is described as the "son of the Dumb Champion". In the poem Baile Suthain Sith Eamhna Lugh is called "descendant of the poet."
