Mailoc or Maeloc was a 6th-century
bishop of
Britonia, a settlement founded by migrating
Britons in
Galicia,
Spain.[1] He represented his diocese, referred to as the Britonensis ecclesia or "Britonnic church", at the
Second Council of Braga in 572. Records of the council refer to his
see, the sedes Britonarum ("See of the Britons"), which may have been seated at the monastery of Saint Mary of Britonia.[1] Mailoc's name is clearly
Brythonic, deriving from the
Celtic *Maglācos, thereby providing further evidence for the Britonnic presence in the area,[1] but he is the only one to have a Celtic name.
