Who they were
Protus and Hyacinth are martyrs of Rome, recorded in the Depositio Martyrum of 354 and buried in the cemetery of Bassilla on the Via Salaria, in an area Pope Damasus dedicated to them. Tradition makes them brothers, slaves of Eugenia, daughter of a prefect of Egypt, who entrusted them to her Christian friend Bassilla to be taught the faith; denounced by her husband, Bassilla was condemned with them.
In 1845 archaeologists found Hyacinth's relics still in the catacomb; they are kept at the College of Propaganda Fide.
The miracles
There was never a formal cause: they have been honoured as martyrs since the fourth century.
Why that counted as sanctity
Two slaves, taught the faith by a Christian woman, gave their lives for Christ with her.
