This limestone Greek Inscription is about four feet tall. It dates to the second century A.D. to honor the governor Julius Publius. Wilson (p. 164) translates the inscription as:
"For good fortune, L(ucius) Calp(urnius) Orestes, chief and financial official of the magnificent colony of Iconium, (honored) Iuius Publius, the most excellent procurator, who surpassed all before him in integrity and fulfillment of the law, (and) also the benefactor of himself and his native city in all things."
