In the voodoo culture, spritis (or usually called "Lwa") are reprensented by symbolic signs to call in the spirit in the voodoo ceremony.
These signs are called "Veve" in the voodoo culture. Erzulie is mostly reprented by a heart, stars, knives and circular lines.
Here are some of the popular veve representing Erzulie Dantor and a few paintings made by Haitian artists.
