Eógan Bél mac Cellaig (died 542[1]) was a king of Connacht from the Uí Fiachrach branch of the Connachta.
The Sligeach bore to the great sea the blood of men with their flesh, They carried many trophies across Eabha, together with the head of Eoghan Bel."
He was buried standing up in pagan style at Ráith Ua Fiachrach on Knocknarea with his red spear in his hand as a challenge to the northern Uí Néill.
[8] The poem also mentions that his son Cellach was a pupil of Saint Ciarán of Clonmacnoise but was treacherously slain by the Uí Fiachrach Aidne.
Prof. Byrne believes that though the poem introduces characters of a later date, it does reflect a tradition of feud between the northern and southern branches of the Uí Fiachrach.
