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