Saci (Brazilian folklore)
Saci (pronounced [saˈsi] or [sɐˈsi]) is a character in Brazilian folklore. He is a one-legged black man, who smokes a pipe and wears a magical red cap that enables him to disappear and reappear wherever he wishes (usually in the middle of a dirt devil). Considered an annoying prankster in most parts of Brazil, and a potentially dangerous and malicious creature in others, he nevertheless grants wishes to anyone who manages to trap him or steal his magic cap. Legend says that a person can trap a Saci inside a bottle when he is in the form of a dust devil (see Fig. right where he is portrayed in the center of the whirlwind).
The Saci legend is seen as a combination of native Tupi lore with African-Brazilian and European myth or superstition combined into it. Also, much of the currently told folklore about the Saci is traceable to what write Monteiro Lobato collected and published in 1917–1918, and the children's book version he created and published in 1921.
According to present-day folklore, this genie can be captured and trapped inside a corked bottle to grant the wishes of its master, or its magic can be acquired by stealing its cap (§ Capturing and subjugating), and the sulfuric smell about the black genie is emphasized, leading to criticism of racism.
