Saint Clement I is invoked as patron of marble workers. Clement I was the third or fourth Bishop of Rome after Saint Peter (the early lists vary in placing him third or fourth), with his pontificate dated by the most reliable ancient witnesses to roughly 88 to 99. He is named in the Roman Canon among the Roman bishops linked directly to the apostles. Sources: https://www.usccb.org/resources/2026cal.pdf.
