Drapo Vodou: Haitian Vodou Flags. Doubtless the most spectacular Haitian art form is the sequin-covered Drapo Vodou or "Voodoo Flag". Vodou is a syncretism of the traditional African religions brought to Haiti by slaves, with the Catholicism of their former masters. The strong influence of Voodoo is in evidence in the sequin designs and patterns of these bottles and flags. Traditionally, they are used to adorn shrines and other places of worship.
