Of the garments worn in everyday life by the Roman citizen, the innermost was the _tunica talaris_, or long tunic. This article of dress was white, usually of wool; it was passed over the head and reached to the feet, the epithet _talaris_ ('reaching to the ankles') being employed to distinguish it, as the tunic of ceremony, from the short tunics worn when freedom was required for active exertion.[20] It fitted tolerably closely to the body, though it was sufficiently loose to require a girdle to confine it. The tunics of senators and _equites_ were distinguished by two bands of purple, in the former case broad (_lati clavi_), in the latter narrow (_angusti clavi_), which passed from the sides of the aperture for the head down to the lower hem of the garment. A comparison of the ecclesiastical _tunica alba_ with the civil _tunica talaris_ will bring out some remarkable points of resemblance. Both were worn in the same manner, and both reached to the feet; it is true that the ecclesiastical dress was slightly fuller than the civil, but this was necessary, as room was required underneath the _alba_ for the wearer's everyday dress. Further, we find ecclesiastics represented in ancient frescoes wearing _albae_ which actually show ornaments disposed like the _clavi_ of the _tunica talaris_. These _clavi_ were early employed by the Christians to distinguish, by their relative width, the representations of Our Lord from those of the Apostles, or to discriminate between the figures of ecclesiastics of different orders. It is also important to notice that the _alba_ is invariably furnished with tight sleeves reaching to the wrist. The tunic was originally a sleeveless garment; but with the growth of luxury, a new kind provided with sleeves gradually came into favour. These two forms of tunic were distinguished by different names: the older or sleeveless tunic was called _colobium_, a Latinization of the Greek name =kolobion=;[21] and the latter or sleeved tunic was named _tunica manicata_ or _tunica dalmatica_, from the name of the province to which its invention was ascribed.
