The yellow/blue cube in f102v2

[davidjackson]

I was intrigued by JKP'sYou are not allowed to view links. Register or Login to view. stating that he thought he could see letters in "the blue cube".
I post this here to keep everything in one thread.

I therefore downloaded the appropriate TIFF from the Beinecke website and ran it through an image process. I altered the colourspace to make certain features in contrast to the paint stand out - no other features were altered, not even image ratios. Here are some results (the colourspace applied is in the file name).

Some accentuate the eva 8 and other the supposed word SAL that JKP mentioned, although it looks more like SAU to me. I attach the clearest ones. I couldn't see anything else apart from the 8 and the SAU word, although there could be some sort of uptick after the 8 glyph?

Note the scratchy form of the SAU word. It was certainly written with a different implement from the main text and even, I suggest the 8 glyph above it. SAU is Occitan for sal, salt.

Note: As these are TIFF images (to preserve the file integrity) the preview function doesn't seem to work on this post. You'll have to download them individually.
