The inscription accompanies and refers to an image of the Nubian god Mandulis wearing his characteristic crown. In addition to the hieroglyphic text there is also a demotic inscription. The demotic one is dated to "the day of the Birth of Osiris, his (?) dedication-festival, year 110 [ Diocletian epoch ]", corresponding to 24 August 394. At the time, Roman Egypt had been largely Christianised, and Egypt was a separate diocese within the Praetorian prefecture of the East.
