"The principal mythological subject in the Second and Third Early Dynastic periods is a god steering a boat that moves of its own accord (126-129)... Scenes such as those in the lower register of 127... often appear below the god in the boat; Frankfort interprets them as depicting the building of a temple tower." Porada, CANES, p. 18-19
