Ancient Seals and Signets
The ancient seal was a stamp or engraving set in stone, metal or some hard substance like crystal. It was usually a symbol or a figure that was used to make an impression on clay or wax, or some other soft substance. It was usually attached to an object like a possession or a document, in order to give it authenticity, ownership or authority. It was used often in the ancient world, especially in Egypt, Babylonia and Assyria and surrounding nations including Israel.
