God name "Murcury"
The name Mercury is connected with the root merx (merchandise) and mercari (to deal, trade). The early Romans, being above all countrymen, had no need for a god of commerce. The Roman Mercury appeared only about the fifth century BCE. and was exclusively the god of merchants. For long he was known only in this capacity so that Plautus, in his prologue to Amphitryon, reminds his audience that Mercury presided over messages and commerce. Like certain other minor divinities - Pecunia, Aesculanus, Argentinus - he watched over tradesmen's profits. Greek
