Miniature art includes paintings, engravings and sculptures that are very small; it has a long history that dates back to prehistory. The portrait miniature is the most common form in recent centuries, and from ancient times, engraved gems, often used as impression seals, and cylinder seals in various materials were very important. For example most surviving examples of figurative art from the Indus Valley civilization and in Minoan art are very small seals. Gothic boxwood miniatures are very small carvings in wood, used for rosary beads and the like.
Western paintings in illuminated manuscripts are known as miniatures, even if not very small - this sense of the word in fact has a different derivation, from a Latin word for a reddish pigment. Miniature art has been made for over 2500 years and is prized by collectors. Museums around the world have collections of miniature paintings, drawings, original prints and etchings, and sculpture.[citation needed]
Miniature art societies, such as the World Federation of Miniaturists (WFM) and Royal Miniature Society, provide applicable of the maximum size covered by the term.[1] An often-used definition is that a piece of miniature art can be held in the palm of the hand, or that it covers less than 25 square inches or 100 cm². Some exhibits require the subjects to be depicted in 1/6 actual size, and in all paintings the spirit of miniaturisation should be maintained.
