LA SIREN maitress la Siren (the mermaid), another form of Erzulie, the Haitian voodum Goddess of love and the wife of Agoue, whose sign or Veve is the whale. The conche shells represent fertility. La Siren entertains herself with music, which is why she has an instrument near her month. This instrument is so pleasant to hear that it puts sailors to sleep on their ships!
