Not a bad talk, from the limited perspective of the modern scholars, who know little. I placed some comments in the comment area, they were deleted, so I include them here.
Daniel Wallace - Tischendorf and the Discovery of the Codex Sinaiticus
An interesting tape. Some notes.
5:25 - "venerated by Christians since the 3rd century" hmmmm.. not likely. A better summary of the early history is here by Walter D. Ward.
Mirage of the Saracen: Christians and Nomads in the Sinai Peninsula in Late Antiquity
20:20 - Tischendorf section begins. Includes the bogus "mouldered by time" claim of Tischendorf.
25:15 - Wallace properly mentions that nothing of any of the Tischendorf claims claims have ever been corroborated by anyone.
25:45 - Wallace is skeptical of what happenned in the 1859 months in Cairo, when Tischendorf claimed to transcribe 100,000 lines of text (with two unamed German helpers)
26:20- "Something in this story just doesn't seem to add up"
29:20 - "all this sounded too good to be true" (read the Secret Mark forgery expose by Stephen Carlson where "too good to be true" is one mark to consider in evaluating forgery)
29:25-32:21 - Simonides section (weak) Tregelles and Bradshaw are used,
31:15 - anachronistic fallacy - "365 animal skins. According to one estimate, the cost of production would be roughly equivalent of a lifetime of work". This is a fallacy because the estimate was dependent on the 4th century economy, not would would be available to a monk on Mt. Athos in the 19th century
31:49 - the vague 1761 Vitaliano Donati reference of a ms. is wrongly said to "match Sinaiticus to a T"
32:09 - New Finds - Wallace does not understand the connection between New Finds materials and ms. efforts of Tischendorf and Uspensky. e.g. Hermas was a special delicate point of Tischendorf and the ending was found in the New Finds. Lots about New Finds
41:35 - Reassessment of the Codex Sinaiticus
46:15 - Accepts Tischendorf fabrication about how he found the ms. in 1859 (monk in cell, the red cloth fabric-ation) even though at:
48:15 - Wallace considers that a Tischendorf story about saving from burning might just be a fabrication
49:15 - "Tischendorf .. his modern Greek was abysmal.. I know the feeling .. no one understood me"
In a longer ending section, Wallace theorizes that the document at Sinai about the 1859 loan may be a forgery. And discusses an evaluation of the signature in a hand-writing comparison. (Tischendorf messed up the 1853 Greek note.) His conclusion seems for authenticity of the document, in an equivocal manner.
