Did you know?
     In ancient Rome a "quincunx" was a coin whose name comes from the Latin 
roots "quinque," meaning "five," and "uncia," meaning "one twelfth." The weight 
of the coin equaled five twelfths of a "libra," a unit of weight similar to 
today's pound. The ancients used a pattern of five dots arranged like the spots 
on dice as a symbol for the coin, and English speakers applied the word to 
arrangements similar to that distinctive five-dot mark.
