Miró claimed to have recently purchased the codex in Extremadura.[18] Extremadura is the province from which Francisco de Montejo and many of his conquistadors came,[3] as did Hernán Cortés, the conqueror of Mexico.[19] One of these conquistadors possibly brought the codex to Spain;[7] the director of the Museo Arqueológico Nacional named the Cortesianus Codex after Hernán Cortés, supposing that he himself had brought the codex to Spain.[19]
