this image is about Sara la Kali, Sara the Black, Saint Sarah, the patron saint of the gypsies. every year in may there is a procession where Sara la Kali is carried out into the sea to re-enact her arrival in france. there are of course various legends about her, the one shown here is the following one:
Another account has Sarah welcoming the Three Marys into Gaul. Franz de Ville (1956) writes:
One of our people who received the first Revelation was Sara the Kali. She was of noble birth and was chief of her tribe on the banks of the Rhône. She knew the secrets that had been transmitted to her… The Rom at that period practiced a polytheistic religion, and once a year they took out on their shoulders the statue of Ishtari (Astarte) and went into the sea to receive benediction there. One day Sara had visions which informed her that the Saints who had been present at the death of Jesus would come, and that she must help them. Sara saw them arrive in a boat. The sea was rough, and the boat threatened to founder. Mary Salome threw her cloak on the waves and, using it as a raft, Sarah floated towards the Saints and helped them reach land by praying.
in front you can see Sara la Kali. to the left of her, is the boat carrying the three marys in the storm, approaching the french coast, to the place which later will be called ´Les Saintes Maries de la Mer`. this lies in the Camargue region, represented by the barren tree, and the flamingo flying over Sara. the angel is the symbol of the vision Sara had.
