The prints are based on drawings by Cortes at the time of arrival in Tenochtitlan. They are reprints- very lovely and rare from more recent editions from the original blocks. The bottom one is a detail of the print based on the drawing that he made the day after they arrived in town. I'm curious why the one at the top is so different.
And this is the city from a satellite in 2006. So many roofs are reddish brown. (If they are ceramic, that would tell me that clay with iron is really common in that area. )
