 In earlier representations (which are not restricted to the Yucatán), the Bacabs who carry the sky are represented by old men carrying the sky-dragon.They can have the attributes of a conch, a turtle, a snail, a spider web, or a bee 'armour'.In the rain almanacs of the Post-Classic Dresden Codex, the old man with the conch and the turtle is put on a par with Chaac.
