other rank of physician, the medicus duplicarius, "medic at double pay", and, as the legion had milites sesquiplicarii, "soldiers at 1.5 pay", perhaps the medics had that pay grade as well. Augustan posts were named according to a formula containing the name of the rank and the unit commanded in the genitive case; e.g., the commander of a legion, who was a legate; that is, an officer appointed by the emperor, was the legatus legionis, "the legate of the legion." Those posts worked pretty much as today; a man on his way up the cursus honorum ("ladder of offices", roughly) would command a legion for a certain term and then move on. The posts of medicus legionis and a medicus cohortis were most likely to be commanders of the medici of the legion and its cohorts. They were all under the praetor or camp commander, who might be the legatus but more often was under the legatus himself. There was, then, a medical corps associated with each camp. The cavalry alae ("wings") and the larger ships all had their medical officers, the medici alarum and the medici triremis respectively. Practice As far as can be determined, the medical corps in battle worked as follows. Trajan's Column depicts medics on the battlefield bandaging soldiers. They were located just behind the standards; i.e., near the field headquarters. This must have been a field aid station, not necessarily the first, as the soldiers or corpsmen among the soldiers would have administered first aid before carrying their wounded comrades to the station. Some soldiers were designated to ride along the line on a horse picking up the wounded. They were paid by the number of men they rescued. Bandaging was performed by capsarii, who carried bandages (fascia) in their capsae, or bags. From the aid station the wounded went by horse-drawn ambulance to other locations, ultimately to the camp hospitals in the area. There they were seen by the medici vulnerarii, or surgeons, the main type of military doctor. They were given a bed in the hospital if they needed it and one was available. The larger hospitals could administer 400–500 beds. If these were insufficient the camp commander probably utilized civilian facilities in the region or quartered them in the vici, "villages". A base hospital was quadrangular with barracks-like wards surrounding a central courtyard. On the outside of the quadrangle were private rooms
