The funerary art of ancient Rome changed throughout the course of the Roman Republic and the Empire and took many different forms. There were two main burial practices used by the Romans throughout history, one being cremation, another inhumation. The vessels used for these practices include sarcophagi, ash chests, urns, and altars. In addition to these, mausoleums, stele, and other monuments were also used to commemorate the dead. The method by which Romans were memorialized was determined by social class, religion, and other factors. While monuments to the dead were constructed within Roman cities, the remains themselves were interred outside the cities.
After the end of Etruscan rule, Roman laws regarding laying the dead to rest became very strict. A major issue was the legality and morality of interring the dead within the city limits. Many Roman towns and provinces had similar rules, often in their charters, such as the Lex Ursonensis.[2] Particularly at the very end of the Republic, exceptions to this principle became more frequent, albeit only for the most powerful leaders. The means used to commemorate the dead served to acknowledge the gods, but also served as means of social expression depicting Roman values and history.
Early Christians continued this custom until Late antiquity, but liked to be buried close to the graves of martyrs. Catacombs and funerary halls, that later became great churches, grew up around the graves of famous martyrs outside the walls of Rome.
