Прав си, този щит е по скоро kite shield отколкото round shield. Порових се малко в нета и разбрах че в античността са се използвали щитове с капковидна форма /на вид като използваните сега от Преследвачите/, които по-късно са се видоизменили в изобразения на твоята картинка. Интересното е че тези щитове са правели само от дърво и кост.
The kite shield was an evolution in the development of shields, representing a change in the popular circular shape which had been dominant in Europe since at least 500 AD. The shield was still in widespread use throughout the 12th century, and is illustrated in art such as on the small Carlton-in-Lindrick knight figurine, but began to be phased out at the end of that century, and had largely disappeared by the 14th century as limb armour became more efficient, and therefore less leg cover was required of shields. Modifications to the kite shield occurred gradually, the top first being truncated, then the tail shortened and the resultant smaller shield that developed is referred to as a heater shield.
