In ancient text and epigraphical records, Marcus Minatius is described as a banker using both Latin and Greek terminology, depending on the context of the source. [1, 2, 3]

• In Latin: He is classified as an argentarius. This standard Roman term refers to a private, professional banker or money dealer who operated commercial banks, extended credit, and managed accounts. [1, 2]
• In Greek Inscriptions: Because his primary historical footprint is on the Greek island of Delos (circa 150 BCE), contemporary inscriptions—such as the famous honorary decree from the Berytian Poseidoniasts—describe him using the Greek equivalent, trapezites (τραπεζίτης). [1, 3, 4]

The inscriptions on Delos explicitly honor Marcus Minatius, son of Sextus, as a "Roman banker" (Ρωμαῖος τραπεζίτης), celebrating his piety and immense financial generosity for advancing capital and donating 7,000 drachmas to help complete their local sanctuary. [1, 2, 3]

If you would like to explore further, I can share more details on how private banking systems functioned in the Roman Republic or provide the specific historical context of the island of Delos as a major trade hub. [, 2, 3]
