In a landscape, two lions approach and attack each other from left and right. The Lion on the right grasps the other's muzzle in its mouth, and is clawing it with its left forepaw. On the back of each lion rides a woman holding in her hand a heart from which sprouts a plant with a Sun flower (left) and a Moon flower (right). The woman on the left holds this heart in her right hand, the woman on the right in her left hand. Behind the woman on the left a knight stands with his sword raised. The lion on the right is followed by four cubs. Gas appears to be coming out of the right-hand lion's anus.
