He had described the machine as something which unbelieving demons invented. When reading from the work of Mardi, it means that during Saladin time, the Muslim had counterweight familiarity but they were not the inventors. What Al-Tarsusi didn’t say is whether the people he believed to be the unbelieving demons were Christians from Europe. Saladin was an active participant from the crusade in most of his career time even though, the manuscripts say that they were either Chinese or Mongolian Weapons.

The counterweight blunderbusses appeared in the history of China records in 1628 after Mongolians attacked Fancheng.
