Object 27 is a kothon (also called an exaleiptron or plemochoe ) from the late 5th or early 4th century BCE. This type of vessel was used to hold cosmetics, oils, or perfumes, either for personal use or in rituals, and was typically made of clay, though a few examples carved out of marble have been found. While the shallow, lidless shape would normally make it hard not to spill the contents of the vessel when moving it, the kothon is designed with an inward curving rim which prevents the liquids inside from sloshing out.
