One of the characteristics of ancient sanctuaries, by which the weary pilgrim was provided with bathing accommodations, is also to be found in the old churches of Rome. We are told in the "Liber Pontificalis" that Pope Symmachus (498-514), while building the basilica of S. Pancrazio, on the Via Aurelia, _fecit in eadem balneum_, "provided it with a bath." Another was erected by the same Pope near the apse of S. Paolo fuori le Mura, the supply of water of which was originally derived from a spring; later from wheels, or noriahs, established on the banks of the Tiber. Notices were written on the walls of these bathing apartments, warning laymen and priests to observe the strictest rules of modesty. One of these inscriptions, from the baths annexed to the churches of SS. Sylvester and Martin, is preserved in section II. of the Christian epigraphic museum of the Lateran. It ends with the distich:-- NON NOSTRIS NOCET OFFICIIS NEC CULPA LABACRI QUOD SIBIMET GENERAT LUBRICA VITA MALUM EST,-- "There is no harm in seeking strength and purity of body in baths; it is not water but our own bad actions that make us sin." These verses are not so good as their moral; but inscriptions like this prove that the abandonment of such useful institutions must be attributed not to the undue severity of Christian morality, but to the ruin of the aqueducts by which fountains and baths were fed. However, even in the darkest period of the Middle Ages we find the traditional "kantharos," or basin, in the centre of the quadri-porticoes or courts by which the basilicas were entered. Such is the vase in the court of S. Cæcilia, represented on the next page, and that in front of S. Cosimato in Trastevere; and such is the famous _calix marmoreus_, which formerly stood near the church of SS. Apostoli, mentioned in the Bull of John III. (A. D. 570), by which the boundary line of that parish was determined. This historical monument, a prominent landmark in the topography of mediæval Rome, was removed to the Baths of Diocletian at the beginning of last year. In many of our churches visitors may have noticed one or more round black stones, weighing from ten to a hundred pounds, which, according to tradition, were tied to the necks of martyrs when they were thrown into wells, lakes, or rivers. To the student these stones tell a different tale. They prove that the classic institution of the _ponderaria_ (sets of weights and measures) migrated from temples to churches, after the closing of the former, A. D. 393.
