Passage 5.25.9
Ἀγαμέμνονι τὸ ὄνομά ἐστι γεγραμμένον· γέγραπται δὲ καὶ τοῦτο ἐπὶ τὰ λαιὰ ἐκ δεξιῶν. ὅτου δὲ ὁ ἀλεκτρυών ἐστιν ἐπίθημα τῇ ἀσπίδι, Ἰδομενεύς ἐστιν ὁ ἀπόγονος Μίνω· τῷ δὲ Ἰδομενεῖ γένος ἀπὸ Ἡλίου τοῦ πατρὸς Πασιφάης, Ἡλίου δὲ ἱερόν φασιν εἶναι τὸν ὄρνιθα καὶ ἀγγέλλειν ἀνιέναι μέλλοντος τοῦ ἡλίου.
The name of Agamemnon is inscribed there; and it is written from right to left. As for the warrior who has a cock as a device upon his shield, he is identified as Idomeneus, the descendant of Minos. Idomeneus traces his lineage from Helios, the father of Pasiphae. They say that the bird is sacred to Helios, and announces beforehand the rising of the sun.
