If you are bewildered about the arts and masterpieces made by the Italian polymath Leonardo da Vinci, and wonder how he might be able to make such pieces, your questions might have the answer. Upon researching, the scientists discovered that Vinci might have an eye condition that allowed him to re-create three-dimensional shapes which he implemented in his sculptures and paintings.
According to the scientists, Vinci might have had a condition called strabismus in which, the person’s eyes are found to be pointing in different directions and they can process a visual scene with only one eye at a time. So, this special disability turned out to be an ability for Leonardo da Vinci to have the special potential of recreating 3-D shapes. Christopher Tyler, University of London, UK, measured eyes in six masterpieces of da Vinci including the famous and most expensive paintings Vitruvian Man and Salvator Mundi. These paintings are thought to be portraits or self-portraits of da Vinci, according to Christopher Tyler.
But, the study which was published in the journal JAMA, Ophthalmology also cites that da Vinci did not have permanent strabismus, but he had an intermittent version of strabismus. He might be switching between seeing like a normal person and also switch to the 3D vision mode. Which essentially means that the special ability allowed da Vinci to switch between two eyes which is also known as stereoscopic vision, due to which he could give him depth perception. While the monocular vision allowed him to interpret a 3-D image on a flat 2-D canvas.
To conclude this, the researcher Tyler fitted circles and ellipses to the pupils, irises on the artwork and then measured the relative positions of these features. “Having strabismus would perhaps explain da Vinci’s great facility for depicting the three-dimensional solidity of faces and objects in the world and the distant depth recession of mountainous scenes,” Tyler said. Tyler also said that many other great artists like Rembrandt and Picasso, who are thought of having the special vision ability of strabismus.
