"Another deity often shown on Akkad seals is the water god, Ea, who bears a vase from which two streams flow over his shoulders; usually there are fishes swimming along these streams. Seals 195-197 embody a frequent theme involving this god--that of a bird-man led captive toward the god ... Seals 199-201 have been interpreted by Frankfort as depicting the victory over Zu, the bird-man, with the water god receiving the joyous news." Porada, CANES, p. 25
