analyses of the radiograph of 'Vista y plano de Toledo' by El Greco

...back to the Old Master that first 'entered' @Lab O, El Greco.
The painting 'Vista y plano de Toledo' is painted on a canvas of which is thought being the same pattern of the canvas he used for 'The Burial of the Count of Orgaz', they look very similar!
Analysing the radiograph shows that both paintings have a canvas with a different pattern.
I saw the painting during my visit to Toledo , you can see the pattern in it.
