Talk:Centre boss
Lenticular centre-boss shields were common -- but harder to make (and therefore expensive). Regional "preferences" are an unlikely explaination. To state that lenticular shields "may have been" used is inaccurate -- they certainly were used from ancient times.
In addition, stuffing the leather or rawhide facing of a shield with grass or straw would have been unlikely in the extreme, as it would not have strengthened the shield in any way, and would have been quickly torn to shreds in combat against edged weaponry. The facing of the shield, whether rawhide or cuir bolli, would have been glued to the shield at all points, thus adding to the structural of the shield itself. Painted canvas covers may then have been added, if only because it was cheaper to replace a tattered canvas cover than strip the rawhide from the shield.
An excellent demonstration of this shield-making technique is in the fourth episode of the History Television documentary series "Weapons that Made Britain" -- definietely worth a watch, as it not only includes period shield-construction, but scientific tests of sheild strength between flat and lenticular centre-bosses -- the lenticular shield takes a full-strength blow from a daneaxe and doesn't fail. The flat centre-boss does.
The Tirksom Bog shield has just such a padding behind the leather and it and also bears the scars of combat. The Ballateare shield fragments bear the paint directly on the leather. There is no evidence for canvas covers to my knowledge.
I am tend to limit my interest in centre boss shields to the late Viking age I will not argue with your knowledge. I am however aware of a single plank from a shield that might be curved and some bosses with have flanges that may indicate that the shield that bore them was lenticular. To the best of my knowledge, their are no lenticular sheild extent today. I am happy to be corrected and would like to know more.
Making a lenticular shield boss is hardly more difficult than making a flat one. The dishing of the boss itself is a far more difficult task than a the slight dishing of a boss suited to a lenticular shield. A boss suited to a curved shield (such as a Norman kite) is more difficult as it involves curves in multiple directions and I had one made for me that fits perfectly from a guy who had made just 6 bosses in his life beforehand. --User 144 19:28, 25 Mar 2006 (CST)
And I guess I don't need to point out that lenticular shields negate some of the benefits of overlapping shields in a shield wall.--User 144 19:52, 25 Mar 2006 (CST)
