Some points on the Translation. As with many translation puzzles I always try to get a couple of translators to have a go at these cartouches and inlays... They are so interesting.
Firstly I have broken it down as the more difficult are in the cartouch but the lower one appears to give the makers name The Work of etc... I will try to have that done in due course...…Whereas there is Persian in the cartouche the long line of work below is from the Holy Koran and is in this case Arabic.
On the longer line of Arabic script I give an example phonetically as
nasrun min allah wa fathun qareeb which means essentially ..With Gods help we will win this battle. I think that is a reasonable line of writing to have on a blade...
