Crementius (or Clementius) is the name of two early Christians:
1. A sub-deacon of Carthage, in connection with Cyprian (Epist. 8).
2. A canonized martyr at Saragossa, about A.D. 304, in the persecution of Diocletian, at the time when Dacian was governor of Spain, having fought twice in the arena, and retired without staining it by his blood (Prudentius, Peristeph. hymn 5, in Migne's Patrol. Lat. 60:982; Ruinart, Acta Sincera Martyrum, page 468; Ceillier, 3:44). Smith, Dict. of Christian Biography, s.v.
