Sigill Lunae, a 9×9 magic square (sum 369), to be inscribed on a silver talisman.
[1] It was first printed in 1591 as part of the tenth and final volume of the collected works of Paracelsus by Johannes Huser of Basel.
Even at this time, the editor expressed doubts as to the text being a genuine work by Paracelsus.
Schneider (1982) has compared the text of all extant manuscript and printed versions with the text of a then-newly discovered early manuscript, with the conclusion that Paracelsian authorship seems "less unlikely" than previously thought, as the presumed original composition may indeed date to the lifetime of Paracelsus (d. 1541), but Schneider still concludes that the work as a whole is "spurious" even though portions (especially the first four books) might indeed be based on writings by Paracelsus, and might be contemporary with Paracelsus' own Neun Bücher Archidoxis (a work on medicine written c. 1526 and first printed in 1567).
The Lesser Key of Solomon, a grimoire of the mid-17th century, is substantially based on the Archidoxis magica.
