In Egyptian hieroglyphs, a cartouche /kɑːrˈtuːʃ/ is an oval with a line at one end tangent to it, indicating that the text enclosed is a royal name. The first examples of the cartouche are associated with pharaohs at the end of the Third Dynasty, but the feature did not come into common use until the beginning of the Fourth Dynasty under Pharaoh Sneferu. While the cartouche is usually vertical with a horizontal line, if it makes the name fit better it can be horizontal, with a vertical line at the end (in the direction of reading). The ancient Egyptian word for cartouche was shenu, and the cartouche was essentially an expanded shen ring. Demotic script reduced the cartouche to a pair of brackets and a vertical line.
