Sencha mac Ailella is a character from the Ulster Cycle of Irish mythology.[1] He acts as an important judge and notable poet during the reign of Conchobar mac Nessa.[2] He volunteered to foster Cúchulainn, but was only an educator.[1][3] Sencha helped establish peace between the Ulstermen.[4]
Sencha's face broke out in "blotches" when giving a misogynistic judgment. They were a consequence of a spiritual or magical ban that compelled him to behave fairly. His face was later healed when Brigit convinced Sencha to reconsider his judgment.[5]
He has been compared to Nestor of Homer's Iliad and Merlin of the Arthurian Legends.[1]
