in antiquity, a military habit worn by the ancients over the Tunic. It belonged to the patricians; and was the same in the time of war, that the toga was in the time of peace. This sort of gown was called ptila, from the rich embroidery with figures of Phrygian work; and purpurea, because the ground-work was purple. The chlamydes of the emperors were all purple, adorned with a golden and embroidered border.
