 Nothing is known about the life of Diogenes apart from the limited information he reveals to us.The inscription itself, which had been dated to the late 2nd century, has now been assigned on epigraphic grounds to the Hadrianic period, 117–138AD.Diogenes was wealthy enough to acquire a large tract of land in the city of Oenoanda to construct (or possibly buy) a piazza to display his inscription.
