What term refers to a name-reminder in Roman society?

In Roman society, a nomenclator was a slave or freedman who served an important role by reminding a prominent individual of the names of people they encountered, especially during public engagements or political events. This was particularly crucial in a society where personal connections and social standing were vital for political maneuvering and networking. The nomenclator would assist their master by ensuring that they remembered names and relationships, which was essential at gatherings or in the political arena to maintain social bonds and alliances.

The other terms listed do not fit this role: a novus homo refers to a person of new wealth or status, usually someone who is the first in their family to achieve a high political office, indicating social ascendency rather than a role of assistance. A praetor was a title for a Roman magistrate with judicial authority, focusing on legal matters, not on social introductions. Lastly, a caupo generally refers to an innkeeper or tavern owner, which does not connect to the concept of remembering names in a social or political context. Thus, nomenclator is the correct term for the name-reminder function in Roman society.
