Abstract
Mohenjo-Daro, the most well-known and largest ruined city of Indus Civilization, is famous for the remarkable municipal water supply and effluent disposal installations. Yet we still know little about the function and significance of the installations and also the sense of the taking a bath in the paving space, where most of archaeologists marked the place as bathroom. The attempt of this paper is to speculate the life-style of the dwellers of Mohenjo-Daro with focusing on the water facilities. From the results of the statistical analyses with respect to the distribution and connection of the wells, the paving spaces, the drains in HR-area, it was illuminated that the drains were instituted in consideration of the paving spaces rather than the wells, and some drains which ran through at the center of the home floor were associated with that the drains were not disliked facilities. The fact that almost the paving spaces are divided into two types; the paving space without drain, well and the paving space attached drain, indicated that the little water of using in the bathing was not only for washing body but also for ablution, religious customs. The study to combine the ecological systems of Mohenjo-Daro, mainly, the Receding-Flood Cultivation based on the Indus River, and the results of the statistical analyses appeared one kind of the eco-social systems of Mohenjo-Daro. In the systems, “flow of water” was the symbol of prosperity and flourishing condition and blessing, such as the city was depend on the flood water from the Indus, the bathing as “flow of water” was a kind of religious customs of worshiping the gods, and the drainage system to flow water was as well a kind of religious installations to produce “flow of water”in the whole city
