Among the discoveries which the Crusaders made and brought home with them one of the most notable was that of the bath, which in its more elaborate forms seems to have been absolutely forgotten in Europe, though Roman baths might everywhere have been found underground. All authorities seem to be agreed in finding here the origin of the revival of the public bath. It is to Rome first, and later to Islam, the lineal inheritor of classic culture, that we owe the cult of water and of physical purity. Even to-day the Turkish bath, which is the most popular of elaborate methods of bathing, recalls by its characteristics and its name the fact that it is a Mohammedan survival of Roman life. From the twelfth century onward baths have repeatedly been introduced from the East, and reintroduced afresh in slightly modified forms, and have flourished with varying degrees of success. In the thirteenth century they were very common, especially in Paris, and though they were often used, more especially in Germany, by both sexes in common, every effort was made to keep them orderly and respectable. These efforts were, however, always unsuccessful in the end. A bath always tended in the end to become a brothel, and hence either became unfashionable or was suppressed by the authorities. It is sufficient to refer to the reputation in England of "hot-houses" and "bagnios." It was not until toward the end of the eighteenth century that it began to be recognized that the claims of physical cleanliness were sufficiently imperative to make it necessary that the fairly avoidable risks to morality in bathing should be avoided and the unavoidable risks bravely incurred. At the present day, now that we are accustomed to weave ingeniously together in the texture of our lives the conflicting traditions of classic and Christian days, we have almost persuaded ourselves that the pagan virtue of cleanliness comes next after godliness, and we bathe, forgetful of the great moral struggle which once went on around the bath. But we refrain from building ourselves palaces to bathe in, and for the most part we bathe with exceeding moderation.[23] It is probable that we may best harmonize our conflicting traditions by rejecting not only the Christian glorification of dirt, but also, save for definitely therapeutic purposes, the excessive heat, friction, and stimulation involved by the classic forms of bathing. Our reasonable ideal should render it easy and natural for every man, woman, and child to have a simple bath, tepid in winter, cold in summer, all the year round.
