Memnon's history encompassed an unknown number of books, but Photius had read the ninth through the sixteenth, and made a tolerably copious abstract of that portion.
The last event mentioned in the sixteenth book was the death of Brithagoras, who was sent by the Heracleians as ambassador to Julius Caesar, after the latter had obtained the supreme power (48 BC).
[clarify] These Excerpta of Photius were first published separately, together with the remains of Ctesias and Agatharchides by Henry Estienne, Paris, 1557.
The best edition is that by Johann Conrad Orelli, Leipzig, 1816, containing, together with the remains of Memnon, a few fragments of other writers on Heraclea.
Memnon's history is valuable as a continuous account of nearly all the Hellenistic period, albeit a compressed one from a local vantage point.
