At Rome, on the old Salarian Way in the cemetery of Basilla, the birthday of the holy martyrs Protus and Hyacinth, brothers, and eunuchs in the service of blessed Eugenia. 

They were arrested in the time of Emperor Gallienus on the charge of being Christians, and urged to offer sacrifice to the gods.  Because they refused, they were most severely scourged and finally beheaded.
