   [Footnote:] *Plutarch's Greek word is exomis, a woollen shirt with the right side open to leave the right arm and shoulder free. —Without any thing, nudus, sometimes means, with only the tunic, or ordinary woollen shirt or under-frock, but here it seems to be almost literal, with only a cloth about the loins, or apron on, a campestre.
