Diamond Mining, Brazil, ca. 1770s
Groups of slaves engaged in various phases of diamond mining, including breaking large stones, supervised/guarded by Europeans. Born in Italy ca. 1740, Juliao joined the Portuguese army and traveled widely in the Portuguese empire; by the 1760s or 1770s he was in Brazil, where he died in 1811 or 1814. For a detailed analysis and critique of Juliao's figures as representations of Brazilian slave life, as well as a biographical sketch of Juliao and suggested dates for his paintings, see Silvia Hunold Lara, Customs and Costumes: Carlos Juliao and the Image of Black Slaves in Late Eighteenth-Century Brazil (Slavery & Abolition, vol. 23 , pp. 125-146). C. R. Boxer, The Golden Age of Brazil, 1695-1750 (Univ. of Calif. Press, 1962) reproduces this painting (in black and white) and dates it 1762.
