the forms it had before a third crown was added to it. For several centuries, popes wore it during processions, as when entering or leaving Saint Peter's Basilica, but during liturgies they used an episcopal mitre instead. Paul VI used it on 30 June 1963 at his coronation, but abandoned its use later. None of his successors have used it. The Ring of the Fisherman, another item of papal regalia, is a gold ring decorated with a depiction of St. Peter in a boat casting his net, with the name of the reigning pope surrounding it. The papal ferula, a staff topped by a crucifix, is the staff used by the pope. America Brazil (Empire of Brazil) The Imperial Crown of Brazil along with other regalia and mementos of the Brazilian Empire are kept at the Imperial Museum of Brazil (Museu Imperial) in the former summer palace of Brazilian emperor Pedro II, in Petrópolis, Brazil. Some pieces are also owned by the jewellery collector Aimée de Heeren, former mistress of President Getúlio Vargas. Chile The Kingdom of Araucania and Patagonia has a crown, presented to Prince Philippe of Araucania in 1986 by a group of Araucanian nobles. Previously, the Royal House had no crown. Made of steel and containing stones from the Biobío River, it is on display at the Museum of the Kings of Araucania, outside the village of Chourgnac d'Ans, Dordogne, France. Mexico Prior to the Spanish conquest (1519–1522) most of present-day Mexico formed the Aztec Empire, a Native American empire ruled from Tenochtitlán (present day Mexico City) by a tlatoani or "emperor". The ceremonial feathered headdress or quetzalāpanecayōtl that was worn by Montezuma II (the last reigning emperor) was seized by the Spanish Conquistadors in c. 1520 and sent back to Charles V, Holy Roman Emperor and King of Spain as a gift. Remarkably, it still survives and Montezuma's headdress can be seen at the Museum of Ethnology, Vienna (inventory number 10402VO) along with other ancient Mexican artifacts. Setting aside the artifacts of Aztec and Spanish rule, there are also extant remnants of the imperial regalia of the First Mexican Empire and Second Mexican Empire.
