Mercury

What's in the name?
The planet Mercury(Originally spelled Mercvrivs) derives its name from the Ancient Roman mythological god of merchants and merchandise, which is often equated with the Ancient Greek mythological god "Hermes". The planetary symbol for Mercury came about in much the same way. It was also used to depict the deity himself as well as in alchemy(the precursor to modern day chemistry) to symbolize the chemical hydargyrum(Originally spelled hydargyrvm), more commonly known as mercury. The symbol for the planet Mercury is shown below.
