It was a favourite implement with the Arabs" and was probably received from the Persians. Muhammad Qasin used it in the capture of the port of Daibal (711-712 A.D.). It required 500 men to operate it and it worked havoc. According to the authority Ibn Kotaibah, this machine was used by Jazynah, the second King of Hyrah, as early as c. 200 A.D. - [Previous: c2.88](https://indike.org/pramana/ins.science.raghavan-1952.c2.88) - [Next: c2.90](https://indike.org/pramana/ins.science.raghavan-1952.c2.90) - [Up: c2](https://indike.org/pramana/ins.science.raghavan-1952.c2) --- Source: [https://indike.org/pramana/ins.science.raghavan-1952.c2.89](https://indike.org/pramana/ins.science.raghavan-1952.c2.89) · Pramāṇa
