Life and Martyrdom
The earliest narrative of the two saints is a Latin text, the Passion of the Martyr Saints Protus and Hyacinth (BHL 2667), composed in Italy between roughly 450 and 499. It describes them as eunuch chamberlains to Saint Eugenia who were baptized alongside her and devoted themselves zealously to the study of sacred Scripture. Before returning to Rome with Eugenia, they are said to have spent time among the Egyptian hermits.
According to the account preserved by the OCA in the life of the Nun-Martyr Eugenia of Rome, Protus and Hyacinthus were Eugenia's original servants, who accompanied her in men's clothing to an Egyptian monastery. As her companions in faith they were later sent to instruct the young noblewoman Basilla. When they were forced into a pagan temple, tradition relates that the idol fell down and was shattered.
Their tradition holds that they refused to renounce their faith and were first scourged and then beheaded. One dating gives the day of their death as 11 September 258; the narrative more broadly sets it in the reign of Emperor Gallienus (260–268). Eugenia herself was martyred on Christmas Day under Gallienus, surviving attempts by drowning, fire, and a pit before being killed by the sword.
Relics & Shrines
The Chronograph of 354 records the burial of the two martyrs in the cemetery (coemeterium) of Basilla on the Via Salaria, later identified as the Catacomb of Sant'Ermete. When Pope Leo IV (847–855) transferred the remains of Roman martyrs to churches within the city, only the grave of Protus was found, and his relics were moved to San Salvatore on the Palatine Hill.
In 1845 Father Giuseppe Marchi discovered the still-undisturbed grave of Saint Hyacinth in a crypt of the same catacomb. The marble-sealed niche contained ashes and pieces of burned bone wrapped in the remains of costly cloth, with an original Latin inscription confirming the traditional date, while fragments bearing the words 'grave of the Martyr Protus' confirmed that both saints had originally shared the burial chamber. By June 1933 the remains of Hyacinth had been relocated to the chapel of the Propaganda College in Rome.
Major shrines associated with the martyrs exist at San Giovanni dei Fiorentini and at the Propaganda College, both in Rome.
Name and Historical Notes
The name of Protus appears in several variant forms, including 'Protatius,' 'Proteus,' and 'Proto'; in England it became corrupted to 'Saint Pratt.' In iconography the two saints are represented as two young men holding the crowns of martyrdom.
Scholars note that the elaborate Passion narrative is likely a novelistic creation, composed to furnish a hagiography for saints whose genuine historical details were unknown and to link them to the likely-fictitious Saint Eugenia. Their historical veneration and burial, however, are attested by the fourth-century Chronograph of 354 and by the archaeological discovery of their graves.
