"Ibn al Haytham's most important contribution
were in the fields of optics, mathematics, and
astronomy. His most important single work is the
comprehensive Kitab al-Manazir (the Book of Optics).
Until the revival of optics in Persia, towards
the end of thirteenth century, Ibn Al-Haythm was
mainly known to the Islamic world as mathematician
and as an astronomer, but his best-known and most
influential work in Europe was the Optics. It
was largely on this bases of his book that George
Satorn described Ibn Al-Haytham as "the greatest
Muslim physicist and one of the greatest students
of optics of all times." Other optical subjects
of Ibn Al-Haytham include: "On the light
of the Moon, that argues that the moon shines
like a self luminous object, though its light
is borrowed from the Sun; On the Halo and Rainbow;
On Spherical Burning Mirrors; On Paraboloidal
Burning Mirrors; and On the Shape of eclipse,
