to the hot baths. This also could have been a result of the depletion of the surrounding forests, resulting in a lack of fuel. The frigidarium, or cella frigidaria consisted of a pool and a host of smaller baths connected to the main room. Water entering the room would come from a pipe or cistern and would exit through a drain within the pool. The water from the pool was thought to have been reused to flush latrines within the complex. The frigidarium was used mainly as a swimming pool or a cold-water bath, depending on the time. Normally, one would continue on to the frigidarium after using the hot-water baths or after exercising in the palaestra. Noting the massive size of the room, it was believed to have also been used as a social room. This idea is supported by the presence of statues and elaborate niches along the walls. On each end of the frigidarium are large shallow pools that were made to be open-air bathing pools. The caldarium The word caldarium comes from the Latin word caleo, meaning "to be hot". The purpose of the caldarium was that of the principal bath chamber within the baths. From its namesake, the room was used for a hot-water bath or for saunas or steam rooms. The room could have also been used for oiling before or after a bath, but, in most cases, this was moved to a separate room off of the caldarium. The caldarium, or cella caldaria, was rectangular in shape with many octagonal rooms found near it in the corner of the structure. The area seemed to be referencing the older Baths of Nero and Titus in its initial design. What set this caldarium apart was the sheer scale of the room compared to its predecessors. It continued a basilica-like theme from the frigidarium with a cross-vaulted middle bay and three projecting apses. These architectural techniques created the feeling of a more open space for the patron. Dressing rooms, also known as apodyteria, were located on either side of the caldarium. Along the sides of the caldarium were private rooms that are believed to have had multiple functions, including private baths, poetry readings, rhetoricians, etc. Other areas attached to the caldarium were a garden, lounging rooms, gymnasiums, and small halls and semicircular exedrae used as lecture and reading rooms.
