Viola is known only through a single mention in Madame Satã's memoirs, where he is described as "the king of capoeira in the port area of Rio." This reference comes from Madame Satã's time at the Central Penitentiary in Rio de Janeiro, suggesting Viola was either a fellow inmate or a figure Madame Satã encountered there through reputation or earlier contact.
The title "king of capoeira" (rei da capoeira) in Rio's port district (zona portuária) indicates Viola held a position of supreme respect among capoeiristas in one of the most historically significant areas for Afro-Brazilian culture in Rio de Janeiro. The port neighborhoods—Saúde, Gamboa, Santo Cristo, and the area around Praça Mauá—constituted "Pequena África" (Little Africa), where African culture, including capoeira, samba, and Candomblé, flourished despite persecution. This was the same region where Prata Preta led the barricades during the 1904 Vaccine Revolt, using capoeira skills to resist police.
Being recognized as "king" in this territory would have required extraordinary fighting ability and social standing among the malandros and capoeiristas who populated the waterfront, the docks, and the surrounding streets. Viola likely worked as a stevedore (estivador) or dock worker, as most capoeiristas in the port area did—these were the men who loaded and unloaded ships and developed their fighting skills in the harsh environment of the docks.
Nothing else is known about Viola—not his full name, specific years of activity, the nature of any crimes that led to his imprisonment, or his fate. His designation as "king" suggests he was a figure of considerable renown in early 20th century Rio, yet he remains almost entirely undocumented, a reminder of how much of capoeira's history has been lost.
