In 1492, Ferdinand II of Aragon adopted the symbol of the Pillars of Hercules and added the Latin warning Non plus ultra meaning "nothing further beyond", indicating "this is the end of the (known) world". But when Christopher Columbus came to America, the legend was changed to Plus ultra, meaning "further beyond". The Pillars of Hercules wrapped in a banner thus became a symbol of the New World. The link between this symbol and the dollar sign is more clearly seen in Spanish coins of the period - which show two pillars, each with a separate banner, rather than one banner spanning both pillars. In this example the right-hand pillar clearly resembles the dollar sign, and additionally directly relates to the use of money.
