Gregory to Peter, Bishop of Aleria in Corsica.
Inasmuch as in the isle of Corsica, at the place Nigeunum, in the possession which is called Cellas Cupias belonging to the holy Roman Church, which by the providence of God we serve, we have ordered to be founded a basilica, with a baptistery, to the honour of the blessed Peter, Prince of the apostles, and of Laurentius the martyr, we therefore hereby exhort thy Fraternity to proceed at once to the aforesaid place, and with observance of the venerable solemnities of dedication to consecrate solemnly the aforesaid church and baptistery. Deposit also reverently the holy relics (sanctuaria) which you have received.
