Cepeda and Carrillo, Relacion universal del desague (Mexico, 1637)

An official dossier on the draining of the Valley of Mexico, printed in Mexico City in 1637 by order of the viceroy Marques de Cadereita and compiled by the Audiencia's relator Fernando de Cepeda with the city's chief notary. It sets out the lakes, the floods, the cut at Huehuetoca and what the work cost — including the crown attorney's printed objection that the labour draft would kill the men sent down the trench, and an inquiry that counted more than sixty thousand Indian workers.
