Thermae
Imperial Baths
Thermae (no singular form) is a Latin term referring to Imperial bathing facilities in ancient Rome. Thermae are perhaps best understood as an evolution of the neighborhood balneae (public bathing facilities) on a more grand scale - though they should not be understood as a replacement for balneae. The first Imperial-level bathing complex was built at the very end of the Republic in 38 BCE by Agrippa, and the first four centuries CE saw the construction of complex after complex as succeeding emperors attempted to build more lavish thermae than the last (Reynolds, 1997). Like balneae, thermae were large complexes fed by aquaeducti that typically contained multiple rooms for bathing, including a cold bath (frigidarium), a warm bath (tepidarium), and a hot bath or steam room (caldarium). They would also have changing rooms where slaves would be stationed to collect, organize, and distribute clothing to visitors before and after their baths, and often thermae had free admission - as opposed to the small fee most balneae charged their bathers. The various bathing rooms would have been heated by a furnace system called the hypocaust which provided heat throughout the complex through channels under the building (Trueman, 2015). Aside from the free admission, what set thermae apart from balneae were their scale, their amenities, and their scarcity. Thermae were massive complexes that gave the visitor far more to do than just bathe. Like balneae, thermae were often places where people would come to meet and socialize, both formally and informally, but the amenities thermae had to offer were on a different scale. Many thermae would be accompanied by palaestrae (a Greek term associated with open areas of gymnasia) that served as exercise spaces for visitors to workout before entering the bathing rooms (Nielsen, reviewed by Fagan, 1992). Thermae were also known for luxurious amenities such as massage rooms, libraries, lecture halls, and other forms of physical and mental stimulation which visitors could enjoy (Reynolds, 1997). While thermae were both more luxurious and less expensive to attend than neighborhood balneae, thermae do not seem to have taken over the role that balneae played in the social fabric of ancient Rome as they became more popular. When Aggripa ordered a census of balneae in Rome in 33 BCE, the number totaled 170. By the 4th century CE, however, that number had reached 856 - despite the fact that this period had seen an explosion of increasingly luxurious thermae being built. This shows that balneae had not only stayed an important part of their communities after the introduction of thermae into Rome, they prospered throughout the city alongside thermae (Reynolds, 1997).
