Minoan seals are impression seals in the form of carved gemstones and similar pieces in metal, ivory and other materials produced in the Minoan civilization. They are an important part of Minoan art, and have been found in quantity at specific sites, for example in Knossos, Malia and Phaistos. They were evidently used as a means of identifying documents and objects.
Minoan seals are of a small size, 'pocket-size', in the manner of a personal amulet. Many of the images are a similar size to a human fingernail, with a high proportion that of the nail of a little finger. They might be thought of as equivalent to the pocket-sized, 1 inch (3 cm) scaraboid seals of Ancient Egypt, which were sometimes imitated in Crete. However Minoan seals can be larger, with largest examples of many inches.
