a) I’m not a scholar. The only reason I know how to do that type of Literary Forensic Analysis, is because I did training as a Forensic Document Analyst.
b) The forensic analysis consists of the following:
i) The specific word that is used:
- When did it first occur in the literature;
- When did it become common usage;
- When did it leave common usage;
- When did it last occur in the literature;
This gives a rough way to date the text;
ii) The grammar of the sentence:
- When was the type of construction first used;
- When was it commonly used;
- When was it last used;
This gives a second way to date the text;
iii) What is the structure of the handwriting:
- When was the copybook first used;
- When was the copybook in common usage;
- When was the copybook last used;
This requires that one either have the original manuscript, or a very good high quality photograph of the text;
This provides a way to date when the copy was made;
iv) Do a full forensic document analysis of the handwriting of the manuscript;
This lets one determine how many people wrote the specific document;
v) Do a statistical analysis of the phrases and words used;
This provides a way to roughly date the text;
vi) Do a statistical analysis of the letters, letter pairs, letter triplets, and letter quadruplets;
This provides a way to differentiate two or more authors;
If I had high quality TIFF/PNG/SVG files, I could do iii and iv.
(JPG files are utterly useless,because they throw away too much data that this type of analysis requires.)
I’ve got the tools on my computer to do everything else.
Most of this is simple grunt work, followed by a different type of grunt work, followed by an argument of whether or not two differences are statistically significant, followed by still more grunt work.
