For a similar hydria in the Harvard University Art Museums, see no. 108 in Mitten and Doeringer, Master Bronzes from the Classical World.
This hydria is likely no. B140 (ex. Geneva Market) listed by von Bothmer in his review of Diehl, Die Hydria, Formgeschichte und Verwendung im Kult des Altertums, in Gnomon, October 1965.
