This window was made of glass "cathedral" and "rollers" that take us back in time. The rollers are blown glass disks with the system of "crown", a method that originated in 500/600 AD and used until the nineteenth century to make the most of the flat glass market. Obtained by the blowing of a sphere and its subsequent compression and expansion for rotation in the oven, always used with lead in the windows. The central part was also called "bullseye" but the word most certainly is closer to us, "funds of the bottle." A full witness is found in the paintings of painters such as Van Eyck, which incorporates this type of glass in many of his works, as treasures to be shown a demonstration of the power attained by the purchasers at the time because few could afford such luxury, Guido Reni in "Birth of the Virgin," but I could mention many others, I leave to you the search!
