Money or monetary.
In the Temple of Juno Moneta ("money," "mint") was housed the Roman mint. The epithet Moneta means "the warner" and refers to an important legend regarding her temple. When Rome was threatened in 390 B.C. by an invasian of Gauls, the sacred geese in Juno's temple began to squawk, rousing the Romans to battle. Moneta, through the Old French moneie, has given us the word money; the adjective monetary, "pertaining to money," comes from the stem monet.
