Great Bath - Necropolis Theory - Supporting evidence

                                                   Close observation of the great bath shows that this structure is entirely made of bricks but no stone is used. No stones are used in the foot steps also. This indicates that this structure was not used on daily basis. Pay attention to any kind of water tank in India, all of them definitely have stone side walls as well as stone foot steps, because when you use these steps on daily basis there will be lot of wear and tear and such kind of brick steps will not suffice. Further, if the water tank is constructed with brick side walls , the bricks will allow the water to seep away as well as the brick will turn into dust in few years time. These observations  show that this Great Bath structure was not used for regular bathing purpose and could have been used for some kind of ceremony. This Great Bath could have been used for ritual bath is also doubtful, because filling water in such a big water tank could have been a difficult task. The second point against the idea of filling-up the tank with water is that it will be almost next to impossible to fill up the tank with manual labour. What ever water you pour into this kind of tank will seep away in few hours. Only a modern high duty, high volume centrifuge pump alone could fill up such a tank.
                                        This idea is supported by the finding of  Hans George Wunderlich, (German Professor of Geology), described in his  book, "Secret of Crete". While contemplating about the mortuary palaces at Knossos at Crete , he concluded that the steps used in those mortuary palaces are made of "White Soft Calcite stones"(Alabaster) (Soft -Soap stones), (Marble stones used in Taj Mahal are harder stones) which could not withstand the rigor of regular usage. He was a Geology Professor and this observation was fundamental to his new theory that those palaces were "Mortuary Palaces" and not "regular palaces" meant for living. This concept is very much applicable to "Indus- Great Bath". From these observations, it can be assumed that this great bath was used for some kind of  ceremony and not as a regular bathing tank. It appears  that this structure is a kind of  inner courtyard (or ) Patio of a building, where rain water is collected and allowed to runoff in a small drain.
