WikipediA: A hydria (Greek: ὑδρία; plural hydriai) is a type of water-carrying vessel in the metalwork and pottery of Ancient Greece. 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.

In this one several handles seem to have broken off.
