Ptolemy assumed an arrangement hay’a that cannot exist, and the fact that this arrangement produces in his imagination the motions that belong to the planets does not free him from the error he committed in his assumed arrangement, for the existing motions of the planets cannot be the result of an arrangement that is impossible to exist Winter, a British historian of science, summing up the importance of Ibn al-Haytham in the history of physics wrote:.

According to this theory, the object being viewed is considered to be a compilation of an infinite amount of points, from which rays of light are projected.

CNRS7 1: According to Ibn al-Haytham, primary light comes from self-luminous bodies and secondary light is the light that comes from accidental objects. He kept a geocentric universe and assumed that celestial motions are uniformly circular, which required the inclusion of epicycles to explain observed motion, but he managed to eliminate Ptolemy’s equant.

Given the progressionof eventsoutlined throughout the preceding sections it seemsunusual that an artist like Alberti was so familiar with the perspectivisr tradition, and yet so little is known about how he arrived at the principles oflinear perspective. Alhazen also wrote a Treatise on the Influence of Melodies on the Souls of Animalsalthough no copies have survived.

The second theory, the intromission theory supported by Aristotle and his followers, had physical forms entering the eye from an object.

This mathematical-physical approach to experimental science supported most of his propositions in Kitab al-Manazir The Optics ; De aspectibus or Perspectivae otics and grounded his theories of vision, light and colour, as well as his research in catoptrics and dioptrics the study of the reflection slhazen refraction of light, respectively.

In his Treatise on PlaceAlhazen disagreed with Aristotle ‘s view that nature abhors a voidand he used geometry in an attempt to demonstrate that place al-makan is the imagined three-dimensional void between the inner surfaces of a containing body.
