Bermuda was discovered in 1503 by Spanish explorer Juan de Bermúdez. It is mentioned in Legatio Babylonica, published in 1511 by historian Pedro Mártir de Anglería, and was also included on Spanish charts of that year. Both Spanish and Portuguese ships used the islands as a replenishment spot to take on fresh meat and water. Legends arose of spirits and devils, now thought to have stemmed from the calls of raucous birds (most likely the Bermuda petrel, or Cahow) and the loud noise heard at night from wild hogs. Combined with the frequent storm-wracked conditions and the dangerous reefs, the archipelago became known as the Isle of Devils. Neither Spain nor Portugal tried to settle it.
