Good afternoon!
I am going to work on the below figure:
I am quite helpless however about the pattern of the banner.
The armour and mainly the helmet shows the time of the First Crusade (1096-1099).
Based on the format of the banner it can be the black/white one with the cross of the Knight Templars.
However it does not fit the timing of the First Crusade, since the foundation of the Templars order is 1119.
So I would be glad to get any suggestion about the pattern of the banner.
