This larger-than-life statue is of Claudia Antonia Tatiana., a local matron, who was honored by the city of Aphrodisias. The statue was found in the Bouleuterion.
Her hairstyle follows that of the empress Julia Domna, and a small Eros stood at her side. The plinth is signed: Alexandros son of Zenon made (this). (from the museum description)
