A symbol

Posted by Frankie on August 23, 2000

This is not exactly a phrase but a symbol.
The pharmaceutical symbol Rx or is it Px?
Two different origins come my way.
1) Px = is short for the latin word prescriptos (misspelled-I know)
meaning "to write".
2) Rx = is an ancient symbol of the planet Mars which was once believed to have had healing powers.

Any light shed is appreciated.
