Saints Proto and Hyacinth: Commemorating the ancient Roman martyrs

The Catholic Church commemorates Saints Proto and Hyacinth on September 11, honoring the ancient Roman martyrs. Their veneration dates back to at least the 4th century, as recorded in the Depositio martyrum.

According to tradition, Proto and Hyacinth were brothers and slaves who assisted the noblewoman Eugenia in spreading Christianity. They were martyred following the conversion of their associate, Bassilla. In the 4th century, Pope Damasus I facilitated the veneration of the martyrs by organizing their burial site along the Via Salaria.

Archaeological findings in 1845 confirmed historical accounts regarding their remains. While the relics of Saint Proto were transferred to the church of San Giovanni dei Fiorentini, the tomb of Saint Hyacinth was discovered intact within the catacombs of Sant’Ermete, containing burnt remains that suggest death by fire.
