Vitalissimo was a Christian martyr who lived during the first century AD. According to an inscription found on his funerary urn, he was a young man of twenty-five years at the time of his death. He died during the Roman persecutions around 100 AD, specifically on June 4. His remains were originally interred in the Catacombs of Cyriaca in Rome, where his martyrdom was evidenced by a small vial of blood kept within his urn.
Relics and transfer
The relics of the saint were once kept in a glass case within a chapel at the Rinuccini Palace in Florence. In October 1858, Eleonora Rinuccini Corsini, the final heir of the noble family, arranged for the body to be moved. This transfer to the church of Faella was intended to allow the local community to better honor and venerate the martyr.
