not exactly, it's not because Linothorax is superrior or any way (indeed speaking protection per weight, linothorax was superrior, but overall protection in close combat (not against missiles), bronze bell cuirass is still better, and the bronze ones are most obviously better in damp seasons.

Linothorax originates from Egypt-Mesopotamian linen armour, and they are adopted first by the Anatolians and Phoenicians before spread to Greek populations through trade and battles. While bronze plate armour with muscles originates from Greece itself.

in the mid of first millenium BC, we can safely argue that Linothorax and bronze cuirass did coexist in Ancient Greek Military system. With linothorax are more popular on lower-to mid class soldiers, Bronze cuirass, has its own artistic values and preferred by Nobles, although some nobles do opt for Scale-reinforced linothorax and greaves (cheaper than bronze armour, but definitely better than plain linothorax)

speaking of vase and photograph, even scenes of illiad do depict people here wearing linothorax as well, while that may be questionable, all we can say is we didn't have enough evidence to either confirm nor deny the existance of linothorax in Greece at 1000 BC
