Tombstones and monuments throughout the Empire document military personnel and units stationed at particular camps "(castra)". If the body could not be recovered, the death could be commemorated with a cenotaph. Epitaphs on Roman military tombstones usually give the soldier's name, his birthplace, rank and unit, age and years of service, and sometimes other information such as the names of his heirs. Some more elaborate monuments depict the deceased, either in his parade regalia or in civilian dress to emphasize his citizenship. Cavalrymen are often shown riding over the body of a downtrodden foe, an image interpreted as a symbolic victory over death. Military funeral monuments from Roman Africa take progressively more substantial forms: steles in the 1st century, altars in the 2nd, and cupulas (mounds) in the 3rd. Tombs were often grouped in military cemeteries along the roads that led out of the camp. A centurion might be well-off enough to have a mausoleum built.
