Greek Lettering - Mosaic Versus Manuscript

Here's two closeup of the lettering of the word MARK or rather MARKOS contrasting how lettering for mosaics and manuscripts differs in "WEIGHT"

This is a closeup of a Byzantine mosaic.

Note the Lunate Sigma and the style of the Alpha. 

Now consider the handwritten letters on this manuscript page and how the letter coloring matches the illustration of the saint writing.

Study how material medium and location influence the layout of the lettering and the shape and weight of letters.

One set on a slightly curved surface made up of smaller tiles and the other written in ink on a tinted background on vellum.

Birthday BG file giveaway

People on my personal FB wall seem to think this might be usable by others?
It's a background texture file. You can edit it anyway you like but some credit or a link back here would be appreciated? It was crafted with Gimp using a combination of 3 filters over a pattern. This will also be available from my Deviant page JVartndesign.
