Theban is a substitution cipher of the Latin alphabet rather than a script in its own right. Each sign stands one for one for a Latin letter, so a Theban text is ordinary language in disguise; the alphabet has no words, no grammar and no sounds of its own. Its earliest known appearance is in Johannes Trithemius's Polygraphia of 1518, a manual of cryptography, and it reached later occultism through his pupil Agrippa, who reprinted it in the Three Books of Occult Philosophy in 1533. Trithemius credited it to Honorius of Thebes, which is the source of the alternative name Honorian, but the ascription rests on his word alone: no surviving manuscript associated with Honorius contains the script, and the alphabet cannot be traced behind 1518. No letter has a name, a numerical value or a symbolic reading in any early source, and modern lists that supply such things are supplying rather than reporting. The forms are compact looping strokes, most closing in a small hook or curled tail. The 1518 set follows the Latin alphabet of its day, which had no separate J, U or W: one sign served for both I and J, another covered U and V, and the signs now printed for J, U and W are later supplements. Modern practice, particularly in Wicca, uses the full twenty-six and knows the cipher as the Witch's Alphabet, used for Books of Shadows, spells and talismanic inscription.

Attributed Author / CompilerNo surviving writing independently attests it before Polygraphia 2 Established by collation rather than assumed from silence. The works of Pietro d'Abano were searched for the passage Trithemius cites and it is not in them, and no manuscript of the Sworn Book of Honorius carries the alphabet except British Library Sloane 3853, which states that it took the characters from Agrippa, Trithemius's own pupil. The letters therefore travel outward from the Polygraphia rather than into it. Attributed Author / CompilerTrithemius ascribed it to Honorius of Thebes, citing Pietro d'Abano 3 Sourced to the subject's own accountTrithemius's own words, printed in the Polygraphia: the alphabet is that of Honorius surnamed the Theban, used to hide the follies of his magic, as Pietro d'Abano testifies in his greater fourth book. That Trithemius wrote this is settled and the Latin has been quoted in a modern edition. Whether the ascription is true is the separate question carried below. Open Questions
Attributed Author / CompilerLikely devised by Trithemius or a contemporary, given a medieval pedigree 2 This one stays open. The investigation that tested the ascription established only that the citation Trithemius gave cannot be traced and that the letterforms are built on the Latin alphabet rather than the Greek, which is consistent with a sixteenth century invention in western Europe but names no maker. Nobody argues for a different origin, so this is a gap in the record and not a dispute between camps. Identity

Trithemius, Honorius and an Unverifiable Attribution
The earliest documented appearance of the Theban script is in the German abbot and cryptographer Johannes Trithemius's Polygraphia, printed in 1518, a serious technical work on cryptography rather than a grimoire in the modern sense. Trithemius attributes the alphabet to a figure he calls Honorius of Thebes, which is the source of the script's alternative name, Honorian, but the attribution rests entirely on Trithemius's own word: no manuscript associated with any historical or legendary Honorius containing this specific script has ever been found, and the alphabet cannot be traced to any source earlier than Trithemius's 1518 publication.
This does not make the alphabet a fraud in the sense of a deliberate forgery aimed at deceiving anyone about its age; sixteenth century cryptographic and magical writers routinely presented newly devised or newly compiled material under the name of an older or more exotic authority, a common convention of the period's literature rather than a unique deception. The honest description is that Theban is a documented sixteenth century substitution cipher whose claimed deeper antiquity is simply unverifiable rather than independently confirmed or refuted.
From Trithemius's Cryptography to the Witch's Alphabet
Trithemius's pupil Heinrich Cornelius Agrippa reprinted the Theban script in his own Three Books of Occult Philosophy in 1533, carrying it from a specialist cryptographic manual into the much more widely read tradition of Renaissance occult literature, and it is largely through Agrippa's reprinting that the script survived into later magical practice at all. From there it continued to circulate through the grimoire tradition for centuries as one cipher alphabet among several, without any single dominant use until its adoption within twentieth century Wicca.
Modern Wiccan practice, from the mid twentieth century onward, took up Theban specifically as a private script for writing a Book of Shadows, the personal record of rituals, spells and correspondences many practitioners keep, on the reasoning that a text written in an unfamiliar script offers a degree of privacy an ordinary Latin alphabet text would not, alongside a general sense of the script's aesthetic fit with magical practice. This use, now commonly called the Witch's Alphabet, is the context in which most people encounter Theban today, a modern application built on a sixteenth century cipher whose own claimed ancient origin remains unverified.

Where does the Theban script come from, and does Trithemius's ascription of it to Honorius of Thebes rest on anything?
The whole case for a medieval Theban script is one sentence in the Polygraphia, and that sentence has been tested. The passage Trithemius cites is not in the works of Pietro d'Abano, and the one manuscript of the Sworn Book of Honorius that carries the alphabet says it took the characters from Agrippa, who was Trithemius's own pupil, so the script travels outward from 1518 rather than into it. What that leaves is an absence: nobody has named who cut the letters, and nobody argues for a rival origin, so this is a gap in the record rather than a dispute between camps. It is one question about one script, which is why it is asked here once rather than twenty six times over the letters.
What would resolve this A witness to the letterforms from before 1518, in the Solomonic, ars notoria or alchemical manuscript traditions, or a systematic survey of those traditions returning nothing, which would be a real answer and not a failure. Failing either, work on Trithemius's own papers establishing whether he devised the script himself.
