The dedication of a square next to the theatre at Corinth by an official named Erastus was ‘in return for his aedileship’ (PRO AEDILIT[AT]E). Erastus would appear to be have made an election promise, and the square, edged with the dedicatory inscription, demonstrated that he had kept to his side of the agreement.
There is a small piazza at Corinth adjacent to the theatre. Along the edge are the remains of an inscription, originally with inset bronze lettering. This reveals that this public facility had been provided by Erastus-the full name is unknown due to the loss of part of the inscription-from his own money in return for being elected as aedile in the colony. Erastus had made an election promise, and the inscription showed that he had fulfilled his obligation.
