Mazandaran dagger
 

I am sorry for Google translate:

"... but the very first known image of such a dagger belonged to the Indian master Bishandas and was painted by him in 1616-1617, when he was in Persia, sent there by Jahangir to the court of Shah Abbas. The image features Saru Taqi, a eunuch and later vizier of the Safavid Empire, but most importantly, the ruler of the Mazandaran province of Iran on the southern shore of the Caspian Sea. After Bishandas returned from Iran, Jahangir is already depicted in his miniatures with this dagger. And in the text “Jahangir-name” at the same time Jahangir writes about one of the gifts: “I gave him a royal (special) dagger in the Mazandaran style”..."

Very interesting!
Thank you!

Thanks for the interesting information
