Knight at Arms
It was not the 1st time ,already noticed those oval shield ,in late french enluminures some of them have weird "3d" monster faces.Waldzios said:I'm not sure , we can add oval shields, but IMHO the illustrations probably show round shields seen from angles, there probably were some oval shields in use , but AFAIK the most Italian museum pieces are standard shape rondache.
Italian harness and rondache from 16th century:
Well few sources I can find instantly :
Zimke if you're interested about sources on "3d" monster face shields I could print stuff.
