Abu Ali Hasan Ibn al-Haitham (known as Alhazen to medieval scholars in the West), born in
Basrah in 965 A.D.. His most important work - though he wrote some 200 books - is held to
be a seven volume series on optics, Kitab al-Manazir, in which he gives the first correct
explanation of vision, showing that light is reflected from an object into the eye. He is
said to have ‘invented’ the camera obscura.

Hadba Minaret, at the Great Nurid Mosque, Mosul, built 1172 A.D by Nurridin Zangi, the
then Turkish ruler. The 59 meter minaret leans 8 feet off the perpendicular. That is how it
earned its Arabic name Al-Hadba (‘the humped’).
