In warm weather the tunic is often the only garment that a Roman wears indoors. In cold weather he will put a second tunic (or two or three extra, as did Augustus) under his outer one. Like the toga the tunic is ordinarily made of white wool, the finer the better, but, unlike the toga, if the wearer is of the nobility, the tunic is never plain. When the owner is an eques a narrow strip of purple (_angusticlavia_), if a senator a broad strip (_laticlavia_), runs down the entire length of the garment both behind and in front. This is the official token of his rank, that all men may reverence his nobility, and one of the chief tasks of a great man’s valets is to hang the toga so that the purple strips on the tunic will always peep out conspicuously from the undergarment. =70. Capes, Cloaks, and Gala Garments.=--The toga and the tunic are the two standard male garments in peace times, but they do not meet every requirement. On festival days, unless the imperial edict is very strictly enforced, most of the younger citizens will be seen streaming to the theater or circus in the _lacerna_. This, at first, was merely a short sleeveless mantle of light stuff thrown over the toga to protect against dust or rain. Presently it was made into a more festive garment, usually of brilliantly dyed wool, and was substituted for the toga outright. There is a hood usually attached and it is convenient, therefore, to wear the lacerna if one is not anxious to be recognized on the streets; it is so very easy to conceal one’s face. In bad weather, and with poor country people in general, however, the _pænula_ is more useful. This is much like the lacerna, a sleeveless (“Shaker”) cloak or cape, also provided with a hood, but always made of coarse heavy material. Most travelers wear the pænula, and it is a common garment for the slaves. Like the pænula in turn is a third type of swinging cloak, but usually cut shorter,--the _sagum_, issued to soldiers. Sometimes it is of rough material for the severest purposes, sometimes it is a truly elegant garment for officers, floating in bright colors over flashing armor. The generals wear a special sagum of conspicuous red, the _paludamentum_. The sagum is, in fact, so decidedly the military cloak that the phrase “changing the toga for the sagum” has become a regular way of saying “being suddenly called to arms.”
