 Early European descriptions of the Boturini Codex describe it as being made of agave paper, but later studies found the codex's paper to be amate.Both are pre-Conquest, the latter being common before the establishment of European paper mills.The Boturini Codex became part of the eponymous Lorenzo Boturini Benaduci during his time in the Viceroyalty of New Spain, from March 1736 to 31 January 1743.
