The two stones of the pillar mark the separating between actual map on the top part, and the line of the Tropic of Cancer marked by the scorpion-crab on the bottom stone.
the stone-line follows neatly from the feet of the large vultures to the "ground" that the sitting heron of the maghreb sits on, which is exactly the latitude that the Tropic of Cancer follows.
