Colorization - what was it's purpose?

[Dunsel]

"Made for others" is not totally certain only because I recall some eccentric American whose hobby was to "forge" ancient manuscripts, just for fun.

And, if it is forged, that puts Wilfred back on the table as a possibility.  Because what we have is an inferred provenance assembled from surviving letters, ownership marks, archival context, and the manuscript's later discovery.  How convenient of Wilfred to just have happened to find that Kircher letter with the manuscript.

For the same reason that people paid tens of thousands of dollars for an NFTs, or for stuffed Beanie Babies bear...

Thankfully, I'm only art impaired, not gullible, but very true.
