May 31: An important day in the history of Christian archaeology

In the annals of the pontificate of Gregory XIII (1572-1585), we read of the discovery -on the 31st of May 1578– of the anonymous catacomb in the Via Anapo, then identified with the cemetery of Priscilla:

Around the same time, outside Porta Salaria, in the excavation of the Pozzolana, the famous Cimiterio di Priscilla, lost since the time of the Goths, was unexpectedly found surrounded by various burials of the Holy Martyrs with inscriptions in different languages. The Pope sent Cardinal Savelli, his Vicar, to certify everything, and many others went there to see the antiquity. Among other things considered worthy of the memory by the French Ambassador Luigi Castegnero, and Marc Antonio Moretto, both men of great learning, was the sepulchre of Leonidas, Father of Origen, deceased more than one thousand three hundred years ago, was recognised“. (Vatican Library, Vat. lat. 12214, Annali di Gregorio XIII, libro VII, tomo II, f. 66).

Even we cannot speak of a true discovery of Christian antiquities (see here for more information), the historical and social importance of this event lies in the fact that it reawakened interest in Christian antiquities among large sections of the population: the crowd in the Vineyard was so large that Pope Gregory XIII was forced to close the gates. Equally important is the influence of this discovery on the scholars of the time, that generation of scholars who found themselves moving from theory to practical knowledge of Christian cemeteries in a very short space of time.
It is to some of them (in particular the Spaniard Alfoncso Chacón – see here) that we owe the copies of the paintings in the catacomb of via Anapo, which are now unfortunately lost.

Visual sources for catacombs explorations in the 16th century – pt. II

In order to continue on analysing the topic of visual sources for the exploration of the Roman catacombs in the 16th century, we present today the manuscript G6, kept in the Vallicelliana Library in Rome.

This is an archival unit of extraordinary importance, which remains unpublished to this day. It consists of 25 sheets, mostly drawn on both sides, and contains late 16th- and early 17th-century copies of some of the paintings in the catacombs of Rome (in particular from those of Domitilla and the Appian Way district), intended for reproduction in Antonio Bosio’s Roma Sotterranea. In addition to these, there are some sheets added later at the time of binding, but evidently of property of Bosio and his editor Giovanni Severano: among these, there is a pen sketch of the full decoration of the so-called niche of the Virgin in the Catacomb of Priscilla, with notes by Severano, discussed here.

(From C. Cecalupo, Giovanni Severano da Sanseverino prete dell’Oratorio e le catacombe romane, in Rivista di Archeologia Cristiana, 95, 2019)

These reproductions in watercolour of some of the paintings of the catacombs were evidently commissioned by Bosio to derive copper basis for the engravings, with the aim of illustrating his Roma Sotterranea. Its structure is not easy to understand and little can be said about the identity of the artists/copyists, who evidently worked in the catacombs without the direct supervision of Bosio. Among the authors, the famous copyists of Bosio are currently considered plausible, Giovanni Angelo Santini (better known as Toccafondo) and Sante Avanzini (for the both of them, more information can be found here).

Visual sources for catacombs explorations in the 16th century – pt. I

As is often mentioned on this site, the importance of visual sources (signatures, drawings, maps, watercolour copies of ancient paintings) in the history of the discovery of Christian catacombs is incredible.
These sources assume greater weight especially for the initial centuries in the history of Christian archaeology, before the advent of photography.


Among the most famous scholars who proceeded massively to copy the paintings of the catacombs they saw in their explorations is the Andalusian Alonso Chacón (1540-1599).

Chacòn can certainly be considered an important ‘chronicler’ of the state of catacomb paintings in the period in which the scholar lived in Rome (1567-1599).This rich heritage of early Christian iconography can be found in the manuscripts of the Vatican Library Vat. lat. 5409. This work, which has never been published, contains precious drawings of catacomb paintings commissioned by the Dominican to several artists and referable to the pictorial apparatuses of the cemetery of via Anapo and the catacombs of Priscilla, Domitilla and the complexes of the via Appia.

From an artistic point of view, the watercolour copies of the paintings commissioned by Chacón do not reflect the original style of the paintings, as they are totally executed in a strongly Baroque style. Even the scenes are sometimes misrepresented.
In spite of these objective limitations, Chacón’s drawings remain a fundamental archaeological testimony (also for their descriptions and captions), as well as an absolutely enjoyable artistic work.

The Vat. lat 5409 manuscript is fully available in digital format on the Vatican Library website, on this page, which we highlight because of the usefulness of having such sources available digitally worldwide.
