Ibn al-Haytham was widely known in late medieval Europe where he was called Alhazen, the Latinized form of his first name Al-Hasan. Concerning him David C. Lindberg writes: "Alhazen was a prolific writer on all aspects of science and natural philosophy. More than two hundred works are attributed to him by Ibn abî Usaybi’a, including ninety of which Alhazen himself acknowledged authorship.
