2.54 · Natural Substances · Metals
bronze, brass, copper generally bronze (an alloy of copper and tin), but in some contexts apparently brass (an alloy of copper and zinc) and perhaps in a few instances copper Most archaeological objects of the Middle East containing copper consist of bronze, and therefore the most accurate translation of χαλκός[a] is in most instances a term for bronze, which is harder than brass and much harder than pure copper. Many languages have technical terms for bronze, brass, and copper, but some simply designate bronze as ‘brown metal,’ brass as ‘bright metal,’ and copper as ‘red metal.’

Collocation: χαλκὸς ἠχῶν
brass gong (an idiom, literally: echoing brass, or: resounding brass) a gong made of brass In a number of languages the equivalent of gong is ‘noisy metal’ or ‘reverberating metal’ or ‘echoing metal,’ but frequently translators have simply used an expression meaning ‘loud bell.’
1 Except for the occurrence of ἀργύριον in the plural (MAT 26:15), it would be possible to derive all of these references to copper (bronze), silver, and gold coins as direct and predictable metonymic correspondences of the respective terms for substances (see 2.54, 51, 49). Since, however, some languages employ clear distinctions between metals as substances and metals when manufactured into the form of coins, the present classification would seem to be more useful.

χαλκός. From meaning ‘‘ bronze”’ generally (1 Cor 131, Rev 1815), χαλκός comes to be applied to ““ bronze-money” (Mk 68, 1241): cf. P Lips I. 106!® (a.p. 98) βλέπε δέ, μηδενὶ ἄλλῳ Bois (/. δῷς) χαλκόν, P Tebt 11. 41479 (ii/A.D.) πέμψῃ μοι τὸν χαλκόν, ἔπι ἔρχομαι, ‘send me the money, since I am μοι πόσου χαλκοῦ δέδωκες αὐτῶι, “let me know how much money you have given to him” (Edd.).
