Evidence: The Gathering

[pocaracas]

And you know this better than those who have studied the actual document because....?

Look at the characters.  They are written in the modern Greek alphabet.  You can easily verify it for yourself.  Check out Ancient Scripts: Greek.  And as I said, the vellum would have deteriorated because of the changes in temperatures and humidity over the past 14 to 16 centuries.

"Preservation[edit]
True vellum is typically stored in a stable environment with constant temperature and 30% (± 5%) relative humidity. If vellum is stored in an environment with less than 11% relative humidity, it becomes fragile, brittle, and susceptible to mechanical stresses; if it is stored in an environment with greater than 40% relative humidity, it becomes vulnerable to gelation and to mold or fungus growth.[11] The optimal temperature for the preservation of vellum is 20 ± 1.5 °C (68 ± 2.7 °F).[citation needed]"

The characters?...
hmmm

From the wiki, an excerpt of the codex:


And here are other examples of greek writing around that time:



They all look greek to me...

And, about the vellum, " Lacking from it are most of the book of Genesis, Hebrews 9:14 to the end, the Pastoral Epistles, and the book of Revelation; these parts were lost by damage to the front and back of the volume, which is common in ancient manuscripts. " (in http://www.bible-researcher.com/codex-b.html).... and also... this is interesting... " The original 20 leaves containing Genesis 1:1–46:28a (31 leaves) and Psalm 105:27–137:6b have been lost and were replaced by pages transcribed by a later hand in the 15th century.[9] 2 Kings 2:5–7, 10-13 are also lost because of a tear to one of the pages." (in the wiki)

Could it be that you have seen these later transcribed leaves?
