Over the door of each cell was a tablet (titulus) upon which was the name of the occupant and her price; the reverse bore the word "occupata" and when the inmate was engaged the tablet was turned so that this word was out. This custom is still observed in Spain and Italy. Plautus, Asin. iv, i, 9, speaks of a less pretentious house when he says: "let her write on the door that she is 'occupata.'" The cell usually contained a lamp of bronze or, in the lower dens, of clay, a pallet or cot of some sort, over which was spread a blanket or patch-work quilt, this latter being sometimes employed as a curtain, Petronius, chap 7. The arches under the circus were a favorite location for prostitutes; ladies of easy virtue were ardent frequenters of the games of the circus and were always ready at hand to satisfy the inclinations which the spectacles aroused. These arcade dens were called "fornices," from which comes our generic fornication. The taverns, inns, lodging houses, cook shops, bakeries, spelt-mills and like institutions all played a prominent part in the underworld of Rome. Let us take them in order: Lupanaria--Wolf Dens, from lupa, a wolf. The derivation, according to Lactantius, is as follows: "for she (Lupa, i. e., Acca Laurentia) was the wife of Faustulus, and because of the easy rate at which her person was held at the disposal of all, was called, among the shepherds, 'Lupa,' that is, harlot, whence also 'lupanar,' a brothel, is so called." It may be added, however, that there is some diversity of opinion upon this matter. It will be discussed more fully under the word "lupa." Fornix--An arch. The arcades under the theatres. Pergulae--Balconies, where harlots were shown. Stabulae--Inns, but frequently houses of prostitution. Diversorium--A lodging house; house of assignation. Tugurium--A hut. A very low den. Turturilla--A dove cote; frequently in male part. Casuaria--Road houses; almost invariably brothels. Tabernae--Bakery shops.
