A hydria (Greek: ὑδρία; plural hydriai) is a type of water-carrying vessel in the pottery of Ancient Greece, and metalwork. The hydria has three handles. Two horizontal handles on either side of the body of the pot were used for lifting and carrying the pot. The third handle, a vertical one, located in the center of the other two handles, was used when pouring water. If the third handle is missing, the type is called a kalpis. This water vessel can be found in both red- and black-figure technique. They often depicted scenes of Greek mythology that reflected moral and social obligations. As well as holding water hydriai could be used for holding ashes in burials and collecting ballots in elections.
By the mid-5th century BC, Greek artisans were also creating hydria from bronze, some of which were elaborately decorated with finely detailed figures. A 6th-century example is in the Historisches Museum, Berne. Such vessels were also known from Minoan pottery.
Regina Vasorum ("Queen of Vases") is a famous late (4th century BC) hydria in the Hermitage Museum, found in Italy.
