Cyllography
Cyllography is the study and practice of carving or engraving on ivory. The term originates from the Greek word "odontos" meaning tooth, and "graphein" meaning to write, referring to the material most commonly used for this art form. While ivory from elephants has historically been the most prominent material, other sources such as walrus tusks, whale teeth, and even bone have also been utilized. Cyllography encompasses a wide range of techniques, including relief carving, intaglio engraving, and scrimshaw, which is a type of engraving on bone or ivory where the design is filled with ink or pigment.
The practice of cyllography has a long history, with examples found in ancient civilizations across the globe.
