An Atikhandas is the belly; for the metres are cattle, and cattle are food, and food is (what fills) the belly, because it is the belly that eats the food: hence when the belly gets the food, it becomes eaten and used up. And inasmuch as this (brick) eats (atti) the metres (khandas), the cattle, it is called Attikhandas, for Attikhandas is really what is mystically called Atikhandas; for the gods love the mystic.
