This tooth of a sperm whale was probably etched and decorated by a sailor on a whaling ship. This art form, known as pictorial scrimshaw began in the early 19th century as a leisure activity for whalers who were often at sea for up to four years. Traditionally the whalers used sailing needles to etch decorations and inscribe messages on walrus tusks and whale teeth, and then fill in the scratches made on the ivory with black ink. This example, perhaps intended as a gift for a loved one, is engraved with the figure of a woman.
