A kalathos is a tall headdress symbolizing prosperity and worn by certain gods and goddesses such as Serapis, Cybele, Demeter and Demeter's daughter Persephone. More accurately it is a basket with a flared top which was used in a domestic context, sometimes referred to as a "bushel measure" for grain. Sometimes it is confused with the Roman modius, also a basket used as a corn measure; or a polos, a thin cylindrical hat worn by some goddesses. The kalathos was typically worn by deities with eastern origins, or when deities are depicted on coins made in eastern mints.
