Pope Celestine I (Latin: Caelestinus or Coelestinus) was Pope from 10 September 422 to his death in 432. According to the Liber Pontificalis, the start of his papacy was 3 November. However, Tillemont places the date at 10 September.
St. Celestine died on 26 July 432. He was buried in the cemetery of St. Priscilla in the Via Salaria, but his body, subsequently moved, now lies in the Basilica di Santa Prassede.
