Macedonian armour

[Dan Howard]

I've gone though some of the recent theads that skirt around this subject but can't find much direct info. Is there a general consensus on the body armour worn by the heavy infantry of Philip and Alexander before the Persian expedition? Linen has been assumed but that is disputed by the latest linothorax discussions. Leather scale has been found in some Macedonian tombs but I'm not sure of the dating of these. Are the helmets and greaves of common soldiers more likely to have been made of bronze or iron?
