The Wikipedia has “Badīʿ az-Zaman Abu l-ʿIzz ibn Ismāʿīl ibn ar-Razāz al-Jazarī (1136–1206, Arabic: بَدِيعُ الزَّمانِ أَبُو العِزِّ بْنُ إسْماعِيلَ بْنِ الرَّزَّازِ الجَزَرِيّ) was a Muslim polymath: a scholar, inventor, mechanical engineer, artisan and artist from the Artuqid Dynasty of Jazira in Mesopotamia.” The text in the museum states “.. this model [that] seems to be working with animal power, whereas in its secret subdivision, the pelton type water wheel and the wooden mill at the top allow the water to be raised.” The Pelton wheel seems to have been invented in the 1870’s AD, making the machine even more difficult to understand (for this photographer).
