Traditionally, the word "tiara" refers to a high crown, often with the shape of a cylinder narrowed at its top, made of fabric or leather, and richly ornamented. It was used by the kings and emperors of some ancient peoples in Anatolia and Mesopotamia, notably the Hittites. The Assyrians used to include a pair of bull horns as a decoration and symbol of authority and a circle of short feathers surrounding the tiara's top. The Persian tiara was more similar to a truncated cone, without the horns and feathers but more jewels, and a conic-shaped tip at its top. In the Roman Catholic Church, the Papal tiara is a high cap surrounded by three crowns and bearing a globe surmounted by a cross worn by the Pope during certain ceremonies, being the symbol of his authority. Since Pope Paul VI set aside his tiara after the Second Vatican Council, the Papal Tiara has not been worn. Pope Benedict XVI even removed the tiara from his coat of arms, replacing it with a mitre (but with some symbolic reference to the symbolism of the tiara, still in use in the Holy See's coat of arms).A tiara is a form of crown. There are two possible types of crown that this word can refer to. While the Papal tiara is a type of a crown, tiaras as a type of an adornment not indicating any specific rank are regularly worn by royal and noble ladies; they are merely pieces of jewelry and can be worn by anyone even though they are most commonly associated with royalty. Queen Elizabeth II is said to have the largest and most valuable collection of tiaras in the world, many of which are heirlooms of the British Royal Family. She is often seen wearing them on state occasions. Her personal collection of tiaras is considered to be priceless.
