The Cultural Complex of Bumba-meu-boi from Maranhao is a ritualistic practice, in which certain key characteristics feature, including the cycle of life, the mystical-religious universe, and the ox itself. Bumba-meu-boi is an expression of musical, choreographic, performing, and ludic expression, in which practitioners' relationship with the sacred is mediated through the figure of the ox. A play popular in Brazil called Bumba Meu Boi was conceived in the 18th century and became a nationwide festival. Essentially, it is a form of social criticism. Lower-class Brazilians mock those of higher social status through a comedic folklore story told in song and dance.
Bumba-meu-boi is heavily charged with symbolism: the practice reproduces the cycle of birth, life, and death, and serves as a metaphor for human existence itself. Bumba-meu-boi can be seen in other Brazilian states, but in Maranhao, Bumba-meu-boi is distinctive by the various styles and groups it includes, and also by the inherent relationship between faith, festivals, and art. Every year, the Bumba groups of Maranhao have reinvented this celebration. They've created the songs, comedies, embroidered ox leather on the costumes, and a calendar of performances and festivities. Divided into five main accents, each has particular characteristics. For about four to eight months after the festival cycle reaches its peak, including rehearsals, the pre-season, baptisms, public performances, and rituals around the ox's death, it culminates in the festival cycle, which has the following stages: rehearsals, the pre-season, baptisms, public performances, and rituals. Currently, Bumba Meu Boi is divided into traditional and modern styles. This practice is a period of renewal of energies, which is transmitted by children's groups, dance workshops, and organically within the group.
During the festival, Sao Luis, the capital of Maranhao, is decorated with colors. The city becomes an open stage where different folkloric groups perform different rhythms. This custom has evolved for more than 200 years. This celebration involves the devotion to saints June S. Joao, Pedro, and Marçal, and is one of the most popular manifestations of popular culture in the state, drawing thousands of people. The ox was placed as a centerpiece because the ox was considered a valuable animal for farming. Since oxen were used in agricultural practice, they were also heavily involved in colonial culture, including bullfighting and calf-dancing. It is believed that these were passed down by Portuguese lower-class families since similar social activities can be traced much further back in Portugal. "Bumba my ox" could be translated literally as "dance my ox".
