Ornamental symbol or figure placed on a prominent part of a ship, usually at the bow. It could be a religious symbol, a national emblem, or a figure symbolizing the ship's name. The custom of decorating a ship probably began in ancient Egypt or India and was followed by the Chinese, Phoenicians, Greeks, and Romans. As early as 1000 BC, the stem- and sternposts were carved and painted to distinguish one ship from another. The Vikings built ships with high bows and a projecting stem bearing a menacing figurehead, similar to the ships of William I the Conqueror as seen in the Bayeux Tapestry. Figureheads have historically varied in size from 18 in. (45 cm) to 8–9 ft (2.5 m). They remained popular until after World War I.
