Leather Cuirass

[Giannis K. Hoplite]

So,Pollux is not refering to Sophocles,but to Xenophon that spolas is a thorax.Where does Xenophon mention the spolas instead of thorax and where does he mention that it is attached by the shoulders?In the way Pollux sais it"kata tous omous ephaptomenos" it is almost clear he is refering to the shoulder flaps.But does xenophon mention shoulder flaps in the spolas?
