The Carat of The Romans and Greeks
The solidus was also a Roman weight unit. There is literary evidence that the weight of 72 coins of the type called solidus was exactly 1 Roman pound, and that the weight of 1 solidus was 24 siliquae. The weight of a Roman pound is generally believed to have been 327.45 g or possibly up to 5 g less. Therefore, the metric equivalent of 1 siliqua was approximately 189 mg. The Greeks had a similar unit of the same value.
Gold fineness in carats comes from carats and grains of gold in a solidus of coin. One solidus = 24 carats, 1 carat = 4 grains, is preserved right up to this day. Woolhouse's Measures, Weights and Moneys of all Nations gives gold fineness in carats of 4 grains, and silver in (pound) of 12 ounces each 20 dwt.

“Could truth perhaps be a woman who has reasons for not permitting her reasons to be seen? Could her name perhaps be—to speak Greek—Baubo?... Oh, those Greeks! They understood how to live: to do that it is necessary to stop bravely at the surface, the fold, the skin, to adore the appearance, to believe in forms, in tones, in words, in the whole Olympus of appearance! Those Greeks were superficial—out of profundity!”
—Friedrich Nietzsche (1844–1900)
