Folio 35v opens the second book, on the simple square; 36r continues the discussion. The two image files below are selected leaves, not the complete 187-image manuscript.
Keep in mind
The beginning and end are defective, and the author is unidentified. This guide follows the library’s catalogue; it does not supply a critical edition or full translation. The planetary arrangement in the explorer comes from Agrippa, not from these two leaves.
