Eyes
The curve of your eyes circles my heart
A round of dance and sweetness
And if I no longer know all that I have experienced
It is because your eyes have not always seen me.
Paul Eluard.

. . . .the ‘Optics’ of the first great experimental scientist, Ibn al-Haytham (965 - c1040), had been translated into Latin by 1230 (at which point Ibn al-Haytham acquired his Western name of Alhazen). It was soon widely available in manuscript and appeared in print in 1572. The puzzle is why Ibn al-Yaytham’s example was not followed more extensively, for it would be difficult to overestimate the significance of his achievement. Using a rigorous experimental method, he refuted the standard extromission theory of sight (that sight made possible by rays that go out from the eye) and defended the intromission theory (that sight is made possible by rays that enter the eye from the object); he produced the first full statement of the law of reflection, and also studied refraction; the designed the first true camera obscura; he made enormous advances toward an understanding of physiology of the eye (although he failed to grasp that an upside-down image is projected through the lens on the retina and at the back of the eye); and he laid the intellectual foundations of the science to artificial perspective. Medieval optics was heavily dependent upon his contribution and he was unquestionably the best example of an experimental scientist before Gilbert. ~ Page 319
