Egypt and its legacy loom large in the writings of the Platonists, especially Plutarch of Chaeronea; yet there is surprisingly little research where historians of philosophy engage Egyptological literature, and vice-versa, in assessing this reception. A helpful corrective has been published by Michael Erler, Martin Andreas Stadler (ed.), Platonismus und spätägyptische religion: Plutarch und die Ägyptenrezeption in der römischen Kaiserzeit. Beiträge zur Altertumskunde, 364. Berlin: De Gruyter, 2017. Elsa Giovanna Simonetti (Durham; KU Leuven) has just published a review of the volume at BMCR; you can check out the review here.
