This is one of the few surviving inscriptions from Alexandria in the last hundred years of Ptolemaic rule; see K. Savvopoulos, in "The Epigraphy of Ptolemaic Egypt", p. 91 ( Google Books ). The version printed in OGIS omitted line 5 of the inscription.
On behalf of king Ptolemaios, the god Neos Dionysos, and his children, the gods Neoi Philadelphoi, for the very great goddess Isis and the very great god Serapis, Nepherōs son of Babays adorned this place to be sacred to the lords the very great gods. Year 29, Pachon 29.
