money of Athens (5). But they Teem to have had 
copper money not long after; for Theophraftus, 
I^emohhenes, and fome of the Comic Poets, quoted 
by Athenaeus and Pollux, mention theChalcus, which 
was the name of the copper coin (6). Many pieces of 
Attic copper are now in being (7); and Vitruvius fays, 
they coined copper Oboles, and quarter Oboles (8). 
Authors differ in the value of the Chalcus ; fome 
fay, it was the fixth part of an Obole (9), others the 
Sth (i)i Pliny (fpeaking of it as a weight) the loth 
(2) ; and Vitruvius, in the place before quoted, fays, 
ibine called the quarter of an Obole Dichalcon, 
others Trichalcon. According to Polybius, it feems 
to have been the Sth part, for he makes a quarter of 
an Obole equal to half a Roman ^^5(3); but the De- 
narius palling for 16 AJJes^ and the Drachm for 6 
Oboles, if a quarter of an Obole was equal to half an 
the Denarius fliouldbe greater than the Drachm, 
which it never was. Polybius, therefore, gives this
