"[Seals] 224-233, which are executed with varying degrees of care, all show the bull kneeling. Usually a seated goddess holds one end of a cord that seems to pass through the gate, while a male attendant, who is standing or kneeling or possibly floating in the air, holds the other end. Exceptions are 224, in which the goddess holds not the rope but a cup ..." Porada, CANES, p. 28
