Spolas? "Subarmalis"?

[Dan Howard]

Dear "Dan Howard", the "Linothorax" was - in the beggining - a cuirass of linen layers... But, as always, people finding many things to "upgrade" their weapons, so the "Linothorax" became ALSO (not ONLY!) from leather too...

How would it be upgrading? Multiple layers of linen offers better protection than a leather cuirass of a similar weight. It probably also cost more.

Do you ALSO have done, a "Pyrgos" ("Wall") shield aswell and long spear, as the Achaeans used to have???

The whole point of this sort of armour was to negate the need for a shield. There is no way that a warrior wearing armour as protective as a Dendra Panoply would have carried a shield. Personally I think it was worn by charioteers and, after examining the armour worn by other charioteers of other cultures, am leaning towards the idea that it was specifically worn by the driver, not the passenger
