I didn't know there were only 5 Letters. Do you know if 5 Letters is all he wrote or was requested to write by the King and Queen? I wonder if he wrote more letters that never reached Spain and are still out there. I find it interesting that he compared Seville to Technochtitlan. I like that you point out that the discovery of the new wold was monumental to trading and also introduction to new foods, crops and spices.
