What term refers to an individual responsible for overseeing funerals in ancient times?

The term that refers to an individual responsible for overseeing funerals in ancient times is "libitinarius." This word comes from Latin, where "libitina" was the goddess of funerals and burial rites. The libitinarius managed all aspects of the funeral process, including preparations for the deceased, the arrangement of the funeral rites, and the coordination with mourners.

In contrast, "conclamatio" relates to the practice of calling out the name of the deceased, often as part of the mourning ritual, but does not refer to the individual overseeing the process. The term "collegia funeraticia" signifies the associations or guilds involved in the funerary practices, rather than a single person. "Rogus," on the other hand, denotes the funeral pyre itself, which is the structure used for cremation, and is not the name for the overseer of the funeral. Thus, the correct answer clearly reflects the role associated specifically with overseeing funerals.
