The key concept in the early modern quantification of the human body was the Iberian ‘Piece of the Indies’ or pieza de Indias in Spanish and peça da India in Portuguese. 16th and 17th century slave traders in the Iberian world made slave bodies measurable and comparable by inventing normalised standards based on ideal height and the visual presence of disease or ‘defects’ from the norm. The concept of the pieza (the piece) allowed for the creation of contracts where investors, providers and the state could prospectively calculate tariff, gains, and risk using quantifiable notions of bodies that had not yet been purchased or evaluated. The concept of ‘the piece of the Indies’ itself was established across the Atlantic basin by the early 1600s when it was associated with pieces of fabric exchanged for slaves in Portuguese trading posts in West Africa. Portuguese officials in San José de Loanda deployed the concept when they tallied fees due to the Portuguese crown for slaves bound for the Americas. The pieza as a measure of the ideal slave body for transportation and labour soon emerged across the Atlantic, Pacific and Indian Oceans, being widely used in Dutch trading records. Slave traders and governmental officials also used the term pieza to refer to other captive bodies from the Indies, most notably ‘Indian’ bodies in the Caribbean.
