Passage 3.19.2
μέγεθος δὲ αὐτοῦ μέτρῳ μὲν οὐδένα ἀνευρόντα οἶδα, εἰκάζοντι δὲ καὶ τριάκοντα εἶναι φαίνοιντο ἂν πήχεις. ἔργον δὲ οὐ Βαθυκλέους ἐστίν, ἀλλὰ ἀρχαῖον καὶ οὐ σὺν τέχνῃ πεποιημένον· ὅτι γὰρ μὴ πρόσωπον αὐτῷ καὶ πόδες εἰσὶν ἄκροι καὶ χεῖρες, τὸ λοιπὸν χαλκῷ κίονί ἐστιν εἰκασμένον. ἔχει δὲ ἐπὶ τῇ κεφαλῇ κράνος, λόγχην δὲ ἐν ταῖς χερσὶ καὶ τόξον.
As for its size, I know of no one who has measured it exactly, but one estimating would probably find it to be about thirty cubits high. This statue is not a work of Bathykles; it is ancient and not crafted with artistic skill. For except for the face and the extremities of the feet and hands, the rest resembles a bronze pillar. On its head it wears a helmet, and in its hands it holds a spear and a bow.
