LACONICUM

A species of dry sweating-bath, introduced from Greece by the Romans towards the end of the Republic. It was specially used to correct the effects of excessive indulgence at the table, by inducing severe perspiration; at the conclusion of the process it was usual to take either a cold plunge or a shower-bath. The dry sweating-bath was taken in a small, circular room, covered with a cupola, and capable of being raised to a high degree of temperature. Its sole light was admitted through a hole in its vaulted roof. Under this opening there hung on chains a bronze shield (clipeus), by elevating and depressing which it was possible to regulate the temperature.
