Linothorax vs Spolas

[Dan D'Silva]

There are also many words in our own language which have undergone changes in meaning (i.e.: "gay"), so it is fair to "assume" some words used in ancient literature could also be somewhat distorted as well (especially in poetry - eg: "forsooth").

Indeed; corselet is another good example. But it is, in the end, just an English word we use to translate thorax. I'm not disagreeing with your overall conclusion that the linothorax probably wasn't the T&Y, only I think it was some kind of chest protector.
