Actors in the 1001 Inventions Exhibition, New York, playing scholars from the House of Wisdom and Muslim civilisation.
The House of Wisdom was known by two names, according to its development stages. When it was a single hall during the time of Harun al-Rashid (763 - 809), it was named Khizanat al-Hikmah (Library of Wisdom), but later, as it grew into Bayt al-Hikmah (House of Wisdom), it housed a large library, which held a great collection of different subjects in many languages.
