A type of hydria, a jar for transporting and serving liquids, named after the Ptolemaic necropolis of Hadra near Alexandria, where large numbers of hydriae were deposited as cinerary urns. They have a large, ovoid body, tall neck, two cylindrical horizontal handles and one vertical handle, and a low foot on a disc or conical base. They may feature decoration on a white ground or painting in dark glaze. The vessel type and local variants such as those produced by Cretan workshops were particularly widespread between the late 4th and early 2nd c. BC.
