This “mon-“ in the word money is almost the same with “moon”. However, the learned etymologists mysteriously fail to go deeper than Juno Moneta to investigate any link between money and moon. OED (http://www.etymonline.com/index.php?allowed_in_frame=0&search=money&searchmode=none ): money , … " from Moneta, a title or surname of the Roman goddess Juno, in or near whose temple money was coined; perhaps from monere "advise, warn" (see monitor[/URL] (n.)), with the sense of "admonishing goddess," which is sensible, but the etymology is difficult. In OED the relation of moon and measuring (time) is mentioned as probable. OED, http://www.etymonline.com/index.php?allowed_in_frame=0&search=moon&searchmode=none moon (n.)[/URL][I[/URL]] O.E. mona[/I], from P.Gmc. *menon- … from PIE *me(n)ses- "moon, month" …. Gk. mene "moon," men "month;" L. mensis "month;" O.C.S. meseci, … O.Ir. mi, Welsh mis, Bret. miz "month"), probably from root *me- "to measure," in reference to the moon's phases as the measure of time. But measuring time is inseparable from keeping records of events, and this is the definition of memory (mneme, in Gr.). On the other hand, the relation between feminity and lunar phases is obvious and thus the association of moon with female goddesses like Juna, Gr. Hera, Hekate, etc. References on the lunar nature of Hera and Juno are found in this WP article http://en.wikipedia.org/wiki/Juno_(mythology) . I can add that a prosonym of Hera was “silver-throned” http://www.perseus.tufts.edu/hopper/text?doc=Perseus:text:1999.04.0057:entry=a)rguro/qronos Juno is multiply connected to the moon via the calendae, menstruation, birth etc. I suppose the people who worshipped Juno “Moneta” were mostly women anxious about their health and fertility, matters that could make the difference between a respected lady and a throw-away. Economic concerns were mostly men’s business and might have been secondary to an ancient lady. We owe the etymology of moneo> Moneta to Cicero but modern scholars (or non-scholars) find the explanation of “warning goddess”>”(monetary system) supervisor goddess” as far-fetched and in OED is cited as “difficult”. This is fair as a fool moon. It is true that coinage was related to various temples (not only Juno’s) as the temples were also treasuries and safes for the various coinage and weight standards. This is something that the early christian fathers disliked. Ioannes Chrysostomus said that “the church is not a gold-smith’s or argyrokopeion”. (Patrologia Graeca, 58, 508). The Greeks called the money “argyrion” (silver) ( http://www.perseus.tufts.edu/hopper...ic+letter=*a:entry+group=297:entry=a)rgu/rion) and the minting/coinage “argyrokopia” (lit. “cutting silver”): http://www.perseus.tufts.edu/hopper/text?doc=Perseus:text:1999.04.0057:entry=a)rgurokopi/a Coinage was introduced to Rome late (c. 3rd c. AD) from the Greek cities of South Italy (http://en.wikipedia.org/wiki/Roman_currency#History) . Silver coins (denarius, sestertius) were the most widely used. Also, the Greek silver coins were already known since classical times to the Italians, and the Athenian silver drachma was still in use, additionally as a weight standard. So, coinage was strongly associated with silver in the material world. But the origin of this "mon-" seems to be the Moon. Silver was and is associated with the moon (as is gold with sun) in myth and magic. Moreover, the meaning “coin” is related to “counting”, which also points to the moon, through many biological and subconscious ways. The association of moon (Gr. μην, men) with memory (Gr. mneme) strongly support this. Therefore, the magico-religious association of coinage with moon and moon-deities seems reasonable. The depiction of a crescent on many ancient Greek and Roman coins may be tertiary in the couple “coin-moon”. The most widely accepted silver drachma of Athens had the owl and a small crescent on the one side. After the above, do you find reasonble that the etymology of money should include references to silver and moon, at least as equally possible as the “warning”.
