The Catacomb of Priscilla on the Via Salaria was used for Christian burials from the late 2nd century through the 4th century. This catacomb, according to tradition, is named after the wife of the Consul Manius Acilius Glabrio; he is said to have become a Christian and was killed on the orders of Domitian. Some of the walls and ceilings display fine decorations illustrating Biblical scenes.
The modern entrance to the catacomb is on the Via Salaria through the cloister of the monastery of the Benedictines of Priscilla. The Catacombs of Priscilla are divided into three principal areas: an arenarium, a cryptoportico from a large Roman villa, and the underground burial area of the ancient Roman family, the Acilius Glabrio.
The wall paintings in this catacomb include images of saints and early Christian symbols, such as the painting reproduced in Giovanni Gaetano Bottari's folio of 1754, where the Good Shepherd is depicted as feeding the lambs, with a crowing cock on His right and left hand.
Particularly notable is the 'Greek Chapel' (Capella Greca), a square chamber with an arch which contains 3rd century frescoes generally interpreted to be Old and New Testament scenes, including the Fractio Panis.
The Priscilla catacombs may contain the oldest known Marian paintings, from the early third century. Mary is shown with Jesus on her lap, and the catacombs may have a depiction of the Annunciation, though the latter has been disputed.
On account of the fact that seven early popes and many martyrs were buried in the cemetery, it was known as the 'Queen of the Catacombs' in antiquity. Two popes were buried in the Catacomb of Priscilla: Pope Marcellinus (296 - 304) and Pope Marcellus I (308 - 309).
Alleged relics of Popes Sylvester I, Stephen I, and Dionysius were exhumed and enshrined beneath the high altar of San Martino ai Monti, in the Esquiline area of Rome. Pope Sylvester I was likely originally buried in San Martino ai Monti, although some sources say his remains were transferred there. An unidentified papal sarcophagus discovered during the demolition of Old Saint Peter's Basilica was attributed to Sylvester I and moved to Nonantola Abbey, near the altar that contains the remains of Pope Adrian III. Other sources describe a combination of Sylvester I and Vigilius in an altar in St. Peter's.References:
Derbent is the southernmost city in Russia, occupying the narrow gateway between the Caspian Sea and the Caucasus Mountains connecting the Eurasian steppes to the north and the Iranian Plateau to the south. Derbent claims to be the oldest city in Russia with historical documentation dating to the 8th century BCE. Due to its strategic location, over the course of history, the city changed ownership many times, particularly among the Persian, Arab, Mongol, Timurid, Shirvan and Iranian kingdoms.
Derbent has archaeological structures over 5,000 years old. As a result of this geographic peculiarity, the city developed between two walls, stretching from the mountains to the sea. These fortifications were continuously employed for a millennium and a half, longer than any other extant fortress in the world.
A traditionally and historically Iranian city, the first intensive settlement in the Derbent area dates from the 8th century BC. The site was intermittently controlled by the Persian monarchs, starting from the 6th century BC. Until the 4th century AD, it was part of Caucasian Albania which was a satrap of the Achaemenid Persian Empire. In the 5th century Derbent functioned as a border fortress and the seat of Sassanid Persians. Because of its strategic position on the northern branch of the Silk Route, the fortress was contested by the Khazars in the course of the Khazar-Arab Wars. In 654, Derbent was captured by the Arabs.
The Sassanid fortress does not exist any more, as the famous Derbent fortress as it stands today was built from the 12th century onward. Derbent became a strong military outpost and harbour of the Sassanid empire. During the 5th and 6th centuries, Derbent also became an important center for spreading the Christian faith in the Caucasus.
The site continued to be of great strategic importance until the 19th century. Today the fortifications consist of two parallel defence walls and Naryn-Kala Citadel. The walls are 3.6km long, stretching from the sea up to the mountains. They were built from stone and had 73 defence towers. 9 out of the 14 original gates remain.
In Naryn-Kala Citadel most of the old buildings, including a palace and a church, are now in ruins. It also holds baths and one of the oldest mosques in the former USSR.
In 2003, UNESCO included the old part of Derbent with traditional buildings in the World Heritage List.
