The story 

After the reconstruction I had made of El Greco’s The Burial of the Count of Orgaz, I was curious if more paintings were on a patterned canvas. 

I found this publication where a graphic of the pattern of the canvas was published

A 17th centuries weaving book, considered the very first weaving manual and the website, published by Kris Bruland, www.handweaving.net has been of great help

The computer generated weave draft was created with Weavelt, software developed to interface with computer-aided handlooms
