Another relatively recent find that's interesting is that it seems like a quality mail provided perfectly sufficient protection against puncture, whether by arrows or spears, which is probably why bodkin arrows in the west and other exotic weapons in the east came into use at all in later periods.
Mail armour provided an effective defence against slashing blows by an edged weapon and penetration by thrusting and piercing weapons; in fact the Royal Armoury at Leeds concluded that "... it is almost impossible to penetrate using any conventional medieval weapon..."

Even some of the ancient Roman mail, alternating between riveted and solid rings in double lines, is thought to have easily rivalled that of medieval counterparts according to metallurgic findings, though blunt trauma is an entirely different matter, of course, which is likely why they came up with lorica segmentata, thought to absorb and distribute shock with less concussion than later periods' plate armours.
Hollywood and fantasy genres have produced immense amounts of bullshit to understate the level of protection armour in the old world provided.
Even the leather cuirass of the classical antiquity might have provided relatively good protection. There are still ongoing experiments to recreate such armour produced in their period's methods and so far the results aren't exactly anything like popular culture would have you believe, ie. "one slash or thrust and you're gone".
