The Book of Secrets is a manuscript dating back to the year 1000. It is a priceless manuscript, as it includes descriptions and drawings of more than thirty ingenious devices including mechanical apparatuses, water clocks, automatic calendars and war machines.
The auspices of the Emir of Qatar, His Highness Sheikh Hamad bin Khalifa Al-Thani, has allowed the funding of an entire research group that, after months of work, has given exceptional results.

The complexity of the manuscript had prevented many experts from interpreting it. Thanks to the competence and the technology of the Italian research center Leonardo3, the manuscript has, for the first time, been transcribed (in Arabic) and translated (into Italian, English and French). Moreover, all its machines have been interpreted and reconstructed.

All the work that has been presented in a permanent exhibition at the Museum of Islamic Art in Doha, and it was one of its main attractions on the occasion of its inauguration on November 22, 2008. The exhibition presents a digital and interactive reconstruction of the manuscript, explaining all its machines to the public, thanks to tridimensional models animated through a holographic touch screen.

Two machines of the Book of Secrets were physically reconstructed: The Fortress Demolisher (Figure 23, f. 35v) and the Clock with Three Characters (Figure 11, f. 21r).
All interpretations of the machines are owed to Leonardo3. The project and exhibition were funded by the Qatar Museums Authority chaired by Her Excellence Sheikh Mayassa bint Hamad bin Khalifa Al Thani and directed by Abdulla Al Najjar.
