The works of Ibn al-Haytham and Abū Rayhān Bīrūnī, a Persian scientist, eventually passed on to Western Europe where they were studied by scholars such as Roger Bacon and Witelo.
Ibn al-Haytham és Abu Rajhan Biruni perzsa tudós művei Nyugat-Európába is eljutottak, ahol olyan tanítók tanulmányozták őket, mint Roger Bacon és Witelo.
