Even two Latin inscriptions around 350 from today's Algeria testify to the keeping and admiration of small particles of the cross.[30] Around the year 455, Juvenal Patriarch of Jerusalem sent to Pope Leo I a fragment of the "precious wood", according to the Letters of Pope Leo. A portion of the cross was taken to Rome in the seventh century by Pope Sergius I, who was of Byzantine origin. "In the small part is power of the whole cross", says an inscription in the Felix Basilica of Nola, built by bishop Paulinus at the beginning of 5th century.
