The term intaglio refers to a small image that has been engraved into a gemstone and is usually set in a piece of jewellery, most commonly a ring. Such artistic form has its origin in Sumer in the 4th millennium BC, with the appearance of cylinder and stamp seals, whereby decorations and patterns were engraved into soft stones.
In Roman and Greek mythology, Pegasus was born from the blood of the gorgon Medusa when slayed by Perseus. The creature was then tamed by the hero Bellerophon and aided him in the battle against Chimera. Pegasus later became associated and obeisance to the god Jupiter. A constellation was named after Pegasus and it was depicted on many paintings, coins and pottery.
