Passage 10.25.11
γέγραφε δὲ καὶ Νέστορα τῇ κεφαλῇ τε ἐπικείμενον πῖλον καὶ ἐν τῇ χειρὶ δόρυ ἔχοντα· καὶ ἵππος κονίεσθαι μέλλοντος παρέχεται σχῆμα· ἄχρι μὲν δὴ τοῦ ἵππου αἰγιαλός τε καὶ ἐν αὐτῷ ψηφῖδες ὑποφαίνονται, τὸ δὲ ἐντεῦθεν οὐκέτι ἔοικεν εἶναι θάλασσα.
He has depicted also Nestor, wearing a cap upon his head and holding a spear in his hand; a horse nearby is presented in a posture about to roll in the dust. Up to the point of the horse there appear a shore and the pebbles upon it; beyond this, however, it no longer resembles the sea.
