Polygraphiae libri sex

Polygraphiae libri sex is Johannes Trithemius's own sixteenth-century primary text, and its documented significance here is narrow and specific: it is the earliest known publication of the Theban alphabet, where Trithemius himself ascribes the script to Honorius of Thebes. This record states plainly that the 1518 edition was not consulted directly for this citation; the priority claim is carried on the authority of the reference works cited alongside it rather than presented as independently verified against the original print. As a primary text it is authoritative for the content of this specific early ascription, not for whether Honorius of Thebes himself actually existed or created the alphabet, which the Sworn Book of Honorius edition addresses directly. Use it to establish the documented earliest print appearance of the Theban alphabet and its ascription; a claim about the ascription's accuracy needs that dedicated source.
