. His work was distinguished by mastery of the Latin language and eloquent phrasing, yet it was soon discovered that he inserted several fictional passages into his works.
Even during Trithemius's lifetime, several critics pointed out the invented sources he used.
His forgery regarding the connection between the Franks and the Trojans was part of a larger project to establish a link between the current dynasty of Austria with ancient heroes. While his colleagues like Jakob Mennel and Ladislaus Suntheim often inserted invented ancestors in their works, Trithemius invented entire sources, such as Hunibald, supposedly a Scythian historian. For his research on monasteries, he utilized “Meginfrid,” an imagined early chronicler of Fulda and Meginfrid's nonexistent treatise ''De temporibus gratiae'' to substantiate Trithemius's ideal of monastic piety and erudition, which were supposed to be the same values shared by the monks of the ninth century. Others opine that Meginfrid was not strictly forgery but the combination of wishful thinking with faulty memory.
In the process though, Trithemius became a famous builder of libraries, which he created in

still lend credence to the idea of a mystic-magical foundation concerning the third volume. Additionally, while Trithemius's steganographic methods can be established to be free of the need for angelic–astrological mediation, still left intact is an underlying theological motive for their contrivance. The preface to the ''
Polygraphia'' equally establishes that the everyday practicability of cryptography was conceived by Trithemius as a "secular consequent of the ability of a soul specially empowered by God to reach, by magical means, from earth to Heaven".

The reason for ''Polygraphia'' and ''Steganographia'' as covertexts being written are unknown. Possible explanations are that either its real target audience was the selected few such as Maximilian, or that Trithemius wanted to attract public attention to a tedious field.
