With attached email note from the librarian at Zagoras:
I'm sending you a photo showing our library's old record for Vossius's edition.
We are still working on an exact handwriting match but what we currently have for our theory that someone in the circle of Callinicus III (IV) wrote the Mar Saba document is:
- demonstrable proof of access to Voss 1646 edition at the Library at Zagora
- interest and familarity with Ignatius by Callinicus and a citation that could only have come from Voss's 1646 work
- the practice of writing extensively into book margins.
- the extremely similar handwriting to Clement letter in Callinicus' circle of associates.
- the dispersion of Callinicus' books.
I think this so far is a compelling narrative, and a good counter-narrative to Smith the Forger developed by Stephen Carlson, Peter Jeffery, Agamemnon Tselikas etc.
