Reconstrucción hipotética de la llegada a España del Códice Trocortesiano en el contexto de la Real Orden de 1752 by Andrés Gutiérrez Usillos

“…The cultural, political and administrative circumstances of the mid-18th century in the viceroyalty of New Spain would explain the sending to Spain of the pre-Hispanic Mayan document known as the Trocortesian Codex. Based on previous data indicating that the codex belonged to the family of the Counts of Cancelada, we hypothetized that the document initial destination was the Royal Cabinet of Natural History of the Mines and Royal House of Geography at Madrid. …”
