“Yemanja is an orisha, originally of the Yoruba religion, who has become prominent in many Afro-American religions. Africans from what is now called Yorubaland brought Yemaya and a host of other deities/energy forces in nature with them when they were brought to the shores of the Americas as captives. She is the ocean, the essence of motherhood, and a protector of children.
The goddess is known as Yemanjá, Iemanjá or Janaína in Brazilian Candomblé and Umbanda religions.
The Umbanda religion worships Iemanjá as one of the seven orixás of the African Pantheon. She is the Queen of the Ocean, the patron deity of the fishermen and the survivors of shipwrecks, the feminine principle of creation and the spirit of moonlight. A syncretism happens between the catholic Nossa Senhora dos Navegantes (Our Lady of the Seafaring) and the orixá Iemanjá of the African Mithology. Sometimes, a feast can honor both.
Gifts for Iemanjá usually include flowers and objects of female vanity (perfume, jewelry, combs, lipsticks, mirrors). These are gathered in large baskets and taken out to the sea by local fishermen. Afterwards a massive street party ensues.”
