La Macarena is the patron saint of Matadors and a favorite of Spanish gypsies.
The Seville-born matador Joselito spent a large portion of his fortune to buy four emeralds for her statue.
When he died in the ring in 1920, the Macarena was dressed as a widow for a month.
Correction from a Reader:
Hello, i'm from Seville. This virgin doesn´t is "La Macarena", is other virgin called "La Amargura", of other "cofradía". Also, this virgin neither is the matadors's patron saint, or the emeralds were donated by Joselito, but Juanita Reina, who lived in that neighborhood.
