I have been trying to find out who might have been able to forge the letter of Clement of Alexandria to Theodore (if that is what it was) in the age of Theosophy (roughly 1878 onwards).
Having previously suggested G R S Mead, who flourished at the cusp between the late 19th and early 20th centuries. While he was a trained scholar I have come to the conclusion that he did not have the calligraphic ability to produce the text that was photographed by Smith. It would be more likely from the hand of a person who was an expert at writing minuscule cursive Greek, either a professional calligrapher (sp?) or an Eastern Orthodox monk.
M Smith, IMHO, also did not have the ability to write in a "manuscript" type hand.
An alternate suggestion was Constantine Simonides, who definitely could have produced this letter out of whole cloth. Yet he supposedly died in 1867, although there is evidence (so I hear) that he faked his own death so he could continue to produce forgeries sold through intermediaries. The alternate date of death is 1890, but search as I may there seem to be absolutely no sources to be found online that say this. There is no evidence I can see that he had theosophic leanings either.
However, if someone had a familiarity with the underground mystic movement that was propagated under the pseudonym "Dionysius the Areopagite," with talk of veiled truths and citations from otherwise unknown books by a certain Hierotheos, that person could I think create the letter. If, that is, they had the skill set stated two paragraphs above.
Does anyone have a suggestion for a resource to help me for "likely suspects?"
Edit: Added comment about Smith's ability to write with a "manuscript" hand.
All other historical discussion, ancient or modern, falls here.
