A road inspector for the Lima Viceroy, Concolorcorvo traveled widely in the Spanish lands of the time. In his Lazarillo de ciegos caminantes, he satirizes the Spanish authorities manhandling of the colonies. His Lazarillo, besides its obvious political objectives, had also a technical dimension, since Concolorcorvo described the local customs of the places he visited. His criticism of the political situation in the colonies, however, did not prevent Concolorcorvo in engaging in a very profound European discourse. He is worried about slow progress
in the colonies stressesing that Indians and blacks were an obstacle for such advancement.
