The tepidarium, as the name would imply, was a room in which a moderately warm bath could be taken and where the process of dry rubbing also took place. In the balneum a hot bath could be taken, originally in a tub, but in later times in a large reservoir; and in the frigidarium a cold plunge could be had. The elæothesium was the anointing room where the body was rubbed with oil and massaged. [Illustration: Floor Plan of the Baths of Pompeii From an old woodcut] A good idea of the general layout of a Roman bath can be gained from the accompanying woodcut, showing the ground floor plan of the baths of Pompeii. The baths, as may be seen by the illustration, are nearly surrounded on three sides by houses and shops. The whole building, which comprises a double set of baths, has six different entrances from the street, one of which, A, gives admission to the smaller set only, which was appropriated to the women, and five others to the male department, of which two, B and C, communicate directly with the furnaces, and the other three, D, E, F, with the bathing apartments, of which F, the nearest to the Forum, was the principal one; the other two, D and E, being on opposite sides of the building served for the convenience of those who lived on the north and east sides of the city. To have a variety of entrances was one of the qualities considered necessary to a well constructed set of baths. [Illustration: Frigidarium. From an old woodcut] Passing through the principal entrance, F, which is removed from the street by a narrow footway, and after descending three steps, the bather finds upon his left hand a small chamber or toilet room, 1, which contains a latrine. From passage, F, he proceeded to covered portico, 2, which ran around three sides of an open court, 3, and this portico and court together formed the vestibule of the baths, in which servants belonging to the establishment, as well as such of the slaves and attendants of the great and wealthy, whose services were not required in the interior, waited. Within the court the keeper of the baths who exacted the fee paid by each visitor, was also stationed, and accordingly in it was found the box for holding the money. The room, 4, which runs back from the portico, might have been apportioned to him, or if not, it might have been a waiting room for the convenience of the better classes while waiting the return of their acquaintances from the interior. In this court, likewise, as being the most public place, advertisements for the theater and other announcements of general interest were posted, one of which, announcing a gladiatorial show, still remains. The passageway, 5, is the corridor which leads from the entrance, E, to the vestibule; and the cell, 6, is a toilet room similar to 1. Number 7 is a passage of communication which leads into the chamber, 8, which served as a room for undressing. This room is also accessible from the street by the door, D, through the corridor,
