Crapaud or Johnny Crapaud.
A Frenchman; so called from the device of the ancient kings of France, three toads erect, saltant. (Guillims Display of Heraldrie, 1611.) Nostradamus, in the sixteenth century, called the French crapauds.
Les anciens crapauds prenderont Sara (Nostradamus). Sara is the word Aras reversed, and when the French under Louis XIV. took Aras from the Spaniards, this verse was quoted as a prophecy.
