A History of Lamellar and Scale Armour in the West

[Kai]

Why do you think the armor choosed by the artists of the Divine Triad was the lamellar, if it was a cheap low cost one?

Such questions do not lead anywhere: the old games of "why did not they do x if y" can be played with any result one wishes... There are hundreds of possible reasons why an artist chose this or that armour in this or that artwork. Associative guessing does not help.
That is why it is so important to unearth actual examples of the armour we are talking about and that is not the case with the Byzantine super-Lamellar of Timothy Dawson irrc. Then an academic test with a well made replica may be possible and only then, after all this we may infer on its protective value.
