بطليموس الرابع
A recent papyrological find from Oxyrhynchus (P.Oxy. LXXI 4808) records that he was a tutor () of Ptolemy IV Philopator, r.221–205 BCE, and suggests that he wrote in the mid to late 3rd century, not, as was hitherto thought, in the late 4th. Luisa Prandi (2012) has recently restated the case for the 'high' dating.
