This article provides a new edition of a scholium to Ælius Aristides’ Egyptian Discourse (§93) attested in the ms. Laur. plut. LX, 3 (f. 156v). The reading allows us to ascertain an explicit reference to Hanno’s Periplous. Furthermore, the article stresses the significance of this scholium, probably linked to Arethas, as it represents the first chronological evidence of the circulation of Hanno’s work and of a manuscript belonging to the so-called Philosophical Collection (Pal. gr. 398).
