Titain has painted on a canvas with a pattern…

Saint John the Evangelist on Patmos

It looks as if the canvas has a herringbone twill pattern. After analysing I found that the draft of the warp is an M W design. Much used in varieties in the canvases I have looked at until now. This textile is woven as a straight draft in the weft.

Titian has painted Venus and Adonis on a canvas with a pattern

It has a very similar pattern as the canvas described above , find more details on https://labo.pt/titian-saint-john-the-evangelist-at-patmos

“Os padrões ocultos nas pinturas de Diego Velázquez”

Looking very much forward to give my first presentation next week for Factum Foundation and Casa Natal de Velázquez. Because of Covid-19 it will be on line.

Last February I applied for a grant at Gulbenkian Foundation but it has not been approved.

I did not know by then that another opportunity was waiting at Factum Foundation…

On 3th of March I wrote:…I felt encouraged to present a proposal for a grant at the Gulbenkian Foundation to decipher the seven canvases with a pattern, as mentioned in this publication. Thanks to all of you who believe in this project.

…where the diagonals do not line up perfectly…

The weave draft of the canvas of “The Burial of the Count of Orgaz”
the first time I saw a draft where the diagonals did not line up.
citation:
“This cannot be attributed to a fault in the use of the pedals, because the reproduction is constant, but to an intentional idea of the weaver’s due to a cause we do not know.
This rhombus may be called <twill based,> of (3.1,3.2, 1.2), which comprises
12 threads and 12 pick in the evolution cycle and needs for its production
12 shaft, operated by twelve pedals. The union ol the pedals to the shalt is done according to the twill base .”

First analyses of two other canvases of El Greco paintings in which it looks as if the diagonals also do not line up!

Interesting is that the same texture was found in an antependium from Middelburg-Nassau -Grimbergen, dated to the first third of the 16th century and in a fragment of linen in the collection of the Abbey in St Truiden in Tongeren, Belgium
