Antiquitatum
Antiquitatum is the genitive plural form of the Latin noun antiquitas, which means antiquity, oldness, or the distant past. As a genitive plural, antiquitatum expresses possession or association and is commonly rendered as "of the antiquities" or "of antiquity" in English. Antiquitas is a third-declension noun; its singular forms are antiquitas (nominative) and antiquitatis (genitive), while the plural forms include antiquitates (nominative) and antiquitatum (genitive). The use of antiquitatum appears in inscriptions and texts whenever a plural concept of antiquity is involved, typically as part of a larger phrase describing objects, periods, or qualities linked to the ancient world.
In scholarly Latin, antiquitatum may occur in titles, descriptions, or catalog entries dealing with ancient artifacts
