SAEDNEWS: Here is a video of the seals of ancient Iranian kings.
SAEDNEWS: Seals were small, engraved devices used to make an impression, usually on clay or wax. Seals came in various shapes, including cones, squares, cylinders, and even animal heads.
Seals were fashioned out of a variety of materials, including bone, limestone, metal, semiprecious stone, or wood. Sometimes the names of the owner and his father were inscribed on the seal. Some seals showed the owner’s title.
In order to authenticate a document, the owner of the seal would press its engraving into the clay, wax, or other soft substance affixed to the document. The substance would then harden and hopefully prevent someone from tampering with the document.
