Martyrs during the persecution of Valerian (257-9). The day of their annual commemoration is mentioned in the "Depositio Martyrum" in the chronographia for 354 (Ruinart, "Acta martyrum", ed. Tatisbon, 632) under 11 September. The chronographia also mentions their graves, in the Coemeterium of Basilla on the Via Salaria, later the Catacomb of St. Hermes. The Itineraries and other early authorities likewise give this place of burial ( De Rossi , "Roma sotterranea", I, 176-7). In 1845 Father Marchi discovered the still undisturbed grave of St. Hyacinth in a crypt of the above- mentioned catacomb. It was a small square niche in which lay the ashes and pieces of burned bone wrapped in the remains of costly stuffs (Marchi, "Monumenti primitivi: I, Architettura della Roma sotterranea cristina", Rome, 1844, 238 sqq., 264 sqq.). Evidently the saint had been burnt; most probably both martyrs had suffered death by fire. The niche was closed by a marble slab similar to that used to close a loculus , and bearing the original inscription that confirmed the date in the old Martyrology :

D P III IDUS SEPTEBR
YACINTHUS
MARTYR

( Buried on 11 September Hyacinthus Martyr ).

In the same chamber were found fragments of an architrave belonging to some later decoration, with the words:

. . . S E P U L C R U M P R O T I M(artyris) . . .

(Grave of the Martyr Protus)

Thus both martyrs were buried in the same crypt. Pope Damasus wrote an epitaph in honour of the two martyrs, part of which still exists (Ihm, "Damasi epigrammata", 52, 49). In the epitaph Damasus calls Protus and Hyacinth brothers. When Leo IV (847-55) translated the bones of a large number of Roman martyrs to the churches of Rome, the relics of these two saints were to be translated also; but, probably on account of the devastation of the burial chamber, only the grave of St. Protus was found. His bones were transferred to San Salvatore on the Palatine. The remains of St. Hyacinth were placed (1849) in the chapel of the Propaganda. Later the tombs of the two saints and a stairway built at the end of the fourth century were discovered and restored.

The Catholic Encyclopedia is the most comprehensive resource on Catholic teaching, history, and information ever gathered in all of human history. This easy-to-search online version was originally printed in fifteen hardcopy volumes.

Designed to present its readers with the full body of Catholic teaching, the Encyclopedia contains not only precise statements of what the Church has defined, but also an impartial record of different views of acknowledged authority on all disputed questions, national, political or factional. In the determination of the truth the most recent and acknowledged scientific methods are employed, and the results of the latest research in theology, philosophy, history, apologetics, archaeology, and other sciences are given careful consideration.

No one who is interested in human history, past and present, can ignore the Catholic Church, either as an institution which has been the central figure in the civilized world for nearly two thousand years, decisively affecting its destinies, religious, literary, scientific, social and political, or as an existing power whose influence and activity extend to every part of the globe. In the past century the Church has grown both extensively and intensively among English-speaking peoples. Their living interests demand that they should have the means of informing themselves about this vast institution, which, whether they are Catholics or not, affects their fortunes and their destiny.
