Nomisma (Ancient Greek:νόμισμα) was the ancient Greek word for "money" and is derived from nomos (νόμος) meaning "'anything assigned,' 'a usage,' 'custom,' 'law,' 'ordinance,' or 'that which is a habitual practice.'"[1]
...but money has become by convention a sort of representative of demand; and this is why it has the name 'money' (nomisma) – because it exists not by nature but by law (nomos) and it is in our power to change it and make it useless.
— Aristotle,Nicomachean Ethics [1133b 1].[2]
The termnomos may also refer to an approximately 8 gram Achaean coin denomination.[3][4]
InModern Greek, the wordnomisma means "currency".[5] It is also a term used bynumismatists when referring to thepieces of money or coin in thepluralnomismata an example of which is theAes rude ofNuma Pompilius (the 2nd King of Rome).[6]
