The gens Mimesia was an obscure Roman family, known almost entirely from a famous inscription on the cistern at the Cathedral of San Rufino in Assisi, dating to the first century BC. Two members of the Mimesia gens are named among six men who built the walls surrounding the cistern, pursuant to a decree of the Roman Senate, and under the supervision of the town magistrates. Their filiations also identify their fathers, providing the names of four Mimesii, and among these four names are two Latin praenomina that are relatively rare in extant records.[1]
