Yesterday, I posted a photo of a shelf of books located in the State Archives of Siena. In the writeup, I neglected to make mention of the amazing artwork that can be found on the walls and ceilings above the shelves. It is quite beautiful and you could tell that a master artist painted them. Looking up at this mural, you would swear that the columns and stonework were real, not a two dimensional rendering. I could only be impressed with the mastery of the painter who created it and how long it must have taken him.
