Orichalcum
(
ὀρείχαλκος). Brass (i. e. an alloy of copper and zinc).
Existing specimens of brass are chiefly coins (
sestertii and
dupondii) of Augustus and his successors, though the alloy was probably made
as early as the second century B.C. (Pliny ,
Pliny H.
N. xxxiv. 2Pliny H. N., 4; and cf.
De
Off. iii. 23, 92). The word
ὀρείχαλκος
(“mountain copper”) occurs first in the Homeric Hymns (
In
Ven. 9), and in the early writers it probably designated any bright metal that had the
appearance of gold. See Rossignol,
Les Métaux dans
l'Antiquité (Paris, 1863); and Blümner,
Technologie, iv. pp. 91, 192 (note), and 193 foll.
