While doing research on cartographic history today, I came upon an Aztec map — drawn around 1540 — documenting the land and holdings of Don Carlos Chichimecatecotl for a litigation following his burning at the stake in 1539. (Good ole Spanish Inquisition) What I found most interesting was that the focus of the litigation was his inventory of grafted trees! Depicted and described in hieroglyphs and pictographs are apple, quince, pear, pomegranate and peach trees… as well as grapes… many grafted by Chichimectacotl himself. (If you click on the picture you can see the grafts in greater detail.) Keep those fire extinguishers handy!
