What term refers to a commemorative monument often found in burial practices?

The term "cenotaphium" refers specifically to a commemorative monument that is erected in honor of a person or group, often in connection with burial practices. These monuments can serve as a symbolic resting place, recognizing individuals who may be interred elsewhere or whose remains are not present. Cenotaphs can often be found in cemeteries, memorial parks, or significant historical sites, distinguishing them as markers that celebrate and remember the deceased.

The other terms presented have different meanings. "Puticuli" refers to the grave pits used in Roman burials, primarily for communal interments. "Ustrina" denotes the places where the dead were cremated, focusing on the act of cremation rather than commemoration. "Columbaria" are structures designed to hold cremation urns, typically containing niches for storing ashes, rather than serving the purpose of commemorating individuals ceremoniously. Each of these terms highlights specific aspects of ancient burial customs, but only "cenotaphium" fits the description of a commemorative monument.
