In Egyptian hieroglyphs, a cartouche is an oval with a horizontal line at one end, indicating that the text enclosed is a royal name, coming into use during the beginning of the Fourth Dynasty under Pharaoh Sneferu, replacing the earlier serekh. While the cartouche is usually vertical with a horizontal line, it is sometimes horizontal if it makes the name fit better, with a vertical line on the left. The Ancient Egyptian word for it was shenu, and it was essentially an expanded shen ring. In Demotic, the cartouche was reduced to a pair of parentheses and a vertical line.
