Unpublished manuscript with 42 original red-chalk drawings. The existing Thimm-aligned record places it circa 1560, while Gelli describes it as around 1730; the record therefore preserves the dating conflict rather than creating a duplicate manuscript work.
Castle places the Palladini manuscript around 1590 and mentions forty-two red-chalk drawings, adding a third dating witness to the already-conflicted record.
Vigeant 1882 dates the unpublished Palladini manuscript around 1570, again describing its 42 original red-chalk drawings. He regrets that it was never printed and says that, although the author follows Agrippa, he merits to stand beside Grassi, Capoferro, and Giganti.
Quality phase 357: current specialist description dates MS 14/10 circa 1600 and suggests Bologna only tentatively. Earlier bibliographic witnesses range from circa 1560/1570/1590 to an outlying circa-1730 claim; the conflict is preserved.
