Ah, yes! That is the gent I was thinking about.  My point was not so much that the Voy was drawn using the camera obscura but that people have to stop thinking of  "early modern" people as akin to cavemen.

I don't think this accurately represents David Hockney's (somewhat 
polemical) theory on this: AFAIK, the kind of camera obscura thought to 
have been occasionally used in the 15th Century didn't involve lenses - 
those came somewhat later in the 16th Century with Della Porta, IIRC.

If you search for "camera obscura" and "history", you'll get numerous hits,

Strictly speaking, we're talking "early modern" here, I think. :-)  But 
yes, I'm forever saying how smart those Quattrocento humanists were. ;-)
