In 1795, without leaving the continent of Europe, Juan Lopez of Spain created a map titled Mapa Geográfico del Gobierno de la Nueva Granada ó Nuevo México con las Provincias de Nabajo y Moqui. The title seemed to suggest a sense of adventure, that it was fine to embrace uncertainty and the unknown. (Click images below to enlarge.)
Although his map reflected locations of Spanish influence, Juan Lopez did not exaggerate the influence. His map reflected areas of coexistence, violence and potential violence.
From thousands of miles away, Lopez charted out vast regions controlled by indigenous nations. He imagined the “Apachería,” the “Teguayo,” the “Provincia de Nabajo.” He imagined Spanish missions and settlements within the lands of the Piros and Queres.
To the east, there were vast grasslands where bison grazed; to the west, great rivers that extended so far that they reached, past the margins of the map, to the Gulf of California.
Juan Lopez’s map was authoritative — not because it was a correct geographical representation — but because it was based on many documentary authorities. Lopez claimed to have consulted many sources:
One source was Juan de Torquemada’s Monarquía Indiana (1723), an extensive seven-volume treatise on indigenous Mexican history, culture and traditions, first published in 1615. Volume 2 contained four chapters on New Mexico, which were based in significant part on the letters of fray Francisco de San Miguel and fray Juan de Escalona, who both had spent time in New Mexico and were critical of Juan de Oñate.
The 1723 printing of Monarquía Indiana contained at least one map.
New Mexico was represented as a huge blank space.
Of all the sources he relied upon, Juan Lopez relied most heavily on the work of the French royal cartographer Jean Baptiste Bourguignon D’Anville. This was due to a genealogical connection.

Years earlier, Juan’s father, Tomas Lopez, had studied cartography under D’Anville and later served as the royal cartographer of Spain. D’Anville and Tomas Lopez practiced “desk cartography,” a method of making maps based on field surveys, formal accounts, and a bit of creative license.
In 1758, while studying in Paris, Tomas Lopez created the Atlas Geographico de la America. He dedicated the atlas to Don Fernando VI, Rey de España y de las Indias [King of Spain and the Indies], whose portrait graced the first page of the book. Chapter 3 featured El Nuevo Mexico, which Tomas described as a fertile land for growing wheat, corn and saffron and where “salvages que llamaban antiguamente Apaches … estan haora mucho mas civilizados” [savages once called Apaches … are now more civilized].
Later in his career, Tomas flourished the corners of his maps of the Americas with dreamy drawings of palm trees, parrots, and alligators. Empire and fantasy overlapped on paper and in life.
In 1780, Tomas created a map of the adventures of Don Quixote, based on the novel by Miguel de Cervantes. Somehow it was fitting that the royal cartographer of Spain would create a map based on fiction critical of the Spanish Empire, written almost two hundred years earlier by a man who suffered through brutal war and captivity and whose petition to live in the Americas was denied.
Cervantes set into motion the creative melding of fact with fiction, laughter with trauma, reality with illusion. This practice flowed into most art forms. 
All in all, the tone of Don Quixote and the Spanish maps of the Americas (and New Mexico) was that the world to be desired was an alternative one. The Spanish people wanted something different — and they were going to get it — whether they had to travel thousands of miles by sea, on land, or in their heads.

 Juan de Torquemada, a Spanish Franciscan priest, learned Nahuatl during his studies in Mexico City and derived much of his knowledge for his treatise from indigenous scholars and teachings. The full title of the treatise was Los veinte y un libros rituales y monarchia indiana.

 As Edith Grossman explained, Don Quixote was “the book that crystallized forever the making of literature out of life and literature, that explored in typically ironic fashion, and for the first time, the blurred and shifting frontiers between fact and fiction, imagination and history, perception and physical reality, or that set the stage for all Hispanic studies and all serious discussions of the history and nature of the novel.
