A quote
In the early days, however, there were few baths, and they were not fitted out with any display. For why should men elaborately fit out that which, costs a penny only, and was invented for use, not merely for delight? The bathers of those days did not have water poured over them, nor did it always run fresh as if from a hot spring; and they did not believe that it mattered at all how perfectly pure was the water into which they were to leave their dirt.
