Vevers, the Call of the Gods
These designs are called vevers and are used to summon the gods. They are drawn with flour on the ground.
At the center of the circle of a voodoo ritual stands the poteau-mitan, the central post through which the gods make their entrance into the ceremony. The frame is the symbol of Agwé, god of the sea and husband of Erzulie. Agwé is generous, faithful, and strong.
