San Claudio died a martyr in Ostia at the time of the Emperor Diocletian and therefore the ancient Roman city of Ostia, in whose image you can see the archaeological evidence, to be important in the history of this saint. The information on his life has reached us through the Roman martyrologist who does not give us much information about him. We know that he lived in the period of Diocletian and that therefore his martyrdom took place during the persecutions of this emperor between the end of the third and the beginning of the fourth century. A.D.
Having converted to Christianity through his brother Massimo, San Claudio must have belonged to an important family, in fact his niece Susanna was noticed by the son of Diocletian himself, Massimiano, who wanted her in marriage. San Claudio, who in the meantime had begun an ascetic life by depriving himself of his possessions and giving them to the poorest, opposed. Precisely because of this opposition, Diocletian had him arrested with his family, exiling them to Ostia. Then came the period of persecutions San Claudio refused to sacrifice to the gods and so he was martyred. His ashes were thrown into the sea of Ostia. Ostia thus became the city of San Claudio over the centuries, which still celebrates it today.
