Final answer:
The Catacomb of Priscilla is located in Rome, Italy, and dates back to late antiquity. It served as a burial place and a locale for Christian worship and artwork, providing insight into early Christian practices and iconography.
Step-by-step explanation:
The Catacomb of Priscilla, dating back to late antiquity (c. 200 - 400 CE), is located in the European city of Rome. These underground burial sites were used by Jews followed by Christians starting in the 3rd century.
As the Roman practice of cremation gave way to inhumation, these catacombs were created in the soft tufo rock beneath the city. They served not only as burial places but also as secret gathering spots for religious ceremonies and the display of early Christian art, such as frescoes and sculptures.
One example of early Christian art from these sites includes the Orant from the Catacomb of Priscilla, which is a fresco that dates from the late 2nd century through the 4th century CE. Such artwork provides valuable insight into early Christian iconography and religious practices during a time when Christianity was not yet the dominant religion of the Roman Empire.
