Xystos enim est graeca appellatione porticus ampla latitudine, in qua athletae per hiberna tempora exercentur; nostri autem hypaethrus ambulationes xysta appellant, quas Graeci paradromidas dicunt
For xystus in its Greek signification is a colonnade of ample breadth where the athletes are trained in the winter; but we give the name of xysta to promenades in the open, which the Greeks call paradromides.
