We don’t have a copy of the actual letter but know of its existence because the letter’s contents were later inscribed on column 4 of the archive wall in the theater at Aphrodisias, which benefited from Zolios’s generosity. Zoilos not only boasted in his status as a former slave, but also his friendship with the emperor. (See Joyce Reynolds, Aphrodisias and Rome [London: Society for the Promotion of Roman Studies, 1982], pp. 96–97; R.R.R. Smith, Aphrodisias I The Monument of C. Julius Zoilos [Mainz am Rhein: Verlag Philipp von Zabern, 1993], p. 10.)
