χ56Χαλκῷ
with a bronze [one]
[Meaning] with an iron [one]. The material itself [is] chalke. But [one says] chalkous statue, the derivative adjective. And the feminine [is] chalke, as with chrysous ["golden"] and chrysos ["gold"].
Χαλκῷ· σιδήρῳ. ὅτι χαλκῆ αὐτὴ ἡ ὕλη. χαλκοῦς δὲ ἀνδριάς, τὸ μετουσιαστικόν. καὶ τὸ θηλυκὸν ἡ χαλκῆ, ὡς χρυσοῦς καὶ χρυσός.
