Sanctuary of San Semetrio: A Hidden Treasure in the Catacombs of Priscilla

Nestled within the ancient burial complex of Priscilla in Rome, the Sanctuary of San Semetrio represents a place of profound spirituality and great historical interest. This page is dedicated to the discovery of this sanctuary, its history, the saints associated with it, and the possible “adventures” its exploration can offer.

Discovering the Sanctuary: History and Devotion

The sanctuary dedicated to San Semetrio stood, as mentioned, within the vast burial complex of Priscilla, an area rich in martyrial memories both in the underground catacomb and the area above. The focal point of the cult was the martyr’s tomb, a place shrouded in mystery.

Identification of the Sepulcher: An Unsolved Enigma

The exact location of the venerated sepulcher of San Semetrio remains a mystery to this day. The “De Locis” mentions this place of worship immediately after the tomb of the martyrs Felice and Filippo, located in the subdial basilica of Silvestro. The Malmesbury Itinerary, however, places Semetrio among the martyrs buried in the underground cemetery, after Crescenzione and Prisca. The “Notitia Ecclesiarum” refers to a “Fimitis” (likely a corruption of the name Semetrio), mentioned right after Prisca, buried in a cubiculum near the exit. These different testimonies make the search for the exact burial site even more fascinating.

San Semetrio: The Forgotten Martyr?

The Hieronymian Martyrology, on the date of May 26th, commemorates the martyr Semetrio. However, the marginal position of this mention in the series of laterculi raises doubts about its authenticity as the martyr’s “dies natalis.” It might be a later addition, derived from the “passio” (Gesta Praxedis et Pudentianae). Despite these uncertainties, the sanctuary is remembered in the 7th-century Itineraries of the city of Rome, testifying to its importance in the religious landscape of the time.

The “Gesta Pudentianae et Praxedis”: Another Source of Information

According to the “Gesta Pudentianae et Praxedis” (Acta Sanctorum, Maii), Semetrio was a presbyter arrested along with 22 other faithful during a liturgical celebration in the titulus of Praxedes. Martyred immediately without trial, they were collected by Praxedes herself and buried in the cemetery of Priscilla on May 26th. This narrative, albeit legendary, offers a glimpse into the life of early Christians and their unwavering faith.

Abandonment and Translation of the Relics

It is hypothesized that the place of worship of San Semetrio fell into disuse during the 9th century, when many sanctuaries in the suburbs (and the Priscilla cemetery itself) ceased to be pilgrimage destinations. This decline was largely due to the translation of the venerated relics into urban churches, a common practice to protect them from raids and to centralize the cult.

Exploring the Sanctuary (Virtually): What Are We Looking For?

Even though the precise location of San Semetrio’s tomb remains unknown, its search can turn into a spiritual and historical adventure. So, what are we looking for when we “explore” the sanctuary?

• Traces of the Past: We look for clues in historical, archaeological, and hagiographic sources that might help us identify the exact location of the sepulcher.
• The Atmosphere of Devotion: We try to imagine the atmosphere of faith and prayer that permeated this place in past centuries.
• The Meaning of Martyrdom: We seek to understand the meaning of the martyrdom of San Semetrio and the other saints buried in the Priscilla cemetery, an example of courage and fidelity to the Gospel.

San Semetrio and the Other Saints of the Priscilla Cemetery

The Priscilla cemetery does not only house the remains of San Semetrio, but also those of many other saints and martyrs, including:

• Saint Prisca: Roman martyr, patron saint of some Italian cities. Her feast is celebrated on January 18th.
• Saint Pudenziana and Saint Praxedes: Sisters, daughters of the Roman senator Pudens, venerated for their charity and for burying martyrs.
• Pope Marcellus I: Pope from 308 to 309, martyred during the persecution of Maxentius.

The presence of these holy figures makes the Priscilla cemetery a place of great importance for the history of Christianity and for popular devotion.

Conclusion: A Sanctuary to Rediscover

The Sanctuary of San Semetrio, despite its physical “invisibility,” continues to be a place of great fascination and profound spirituality. Its history, intertwined with that of the Priscilla cemetery and its saints, invites us to rediscover the roots of our faith and to reflect on the meaning of martyrdom and Christian witness.
