Yes, the author of the manuscript names some kind of swords known to him: Sinhalese, Khazar, Byzantine, Yemeni, Kashmir, Chinese and even Russian. But, firstly, the manuscript itself is largely a fantasy text (the sword was invented by Jamshid), and secondly, as it is usually in the case of medieval Persian-language manuscripts, it conveys not actual and reliable information, but retells the beliefs and legends of the past or information from previous manuscripts.

Ya'qûb ibn Ishâq al-Kindi could have sued Fakhr-i Mudabbir for plagiarism. And easily won the case
