A figurehead is a large wooden model of a person that was put just under the pointed front of a sailing ship in former times. 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
