"...Now do you not see that the eye embraces the beauty of the whole world? It is the lord of astronomy and the maker of cosmography, it counsels and corrects all the arts of mankind, it leads men to the different parts of the world, it is the prince of mathematics, and the sciences founded on it are absolutely certain. It has measured the distances and the sizes of the stars, it has found the elements and their locations; it has given birth to architecture, and to perspective and to the divine art of painting. Oh excellent thing, superior to all others created by God! ....What peoples, what tongues will fully describe your true function? The eye is the window of the human body through which it feels its way and enjoys the beauty of the world. Owing to the eye the soul is content to stay in its bodily prison, for without it such bodily prison is torture"Leonardo da Vinci (1452-1519)
Glory be to Allah, the Creator of all.
