historical findings contd.

in my past blogs i wrote the historical recrds with comparison to latest technology. i made clear that the science was advanced in those days,but could not be preserved for future. i feel that the civilization at many places vanished at many places and nobody left to point the locations of sites,forts, palaces,temples,mosques,churches. now the explorers are finding out the real sites. this will definitely bring the information of then architecture and technology. excavations sometimes clear those days civilization as it was found in the excavation of mohanjadaro, harrappa, and many places elsewhere. many sites of the time of lord krihna are still to be excavated. lot of information is under debris of old sites and building which was later occupied in new construction. still near many sites which are remembered passig from generation to other. many sites of old forts was bulit on old sites due to its technical importance. example agra fort on a weak structure remains which cold not bear the attacks. . though on new constuction few signs of the time of construction was preserved by those days circulating coins or inscritions. it was not economical to remove old debris or remains. it was not economical. new buildind are tried to be made on high pltform for safety and sometimes beauty. sikandra was made near the site of palace of sher shah suri. the advantage is that nearby areas of such places are developed. rulers had less time for construction so they use to choose sites demolished or fallen and the places they got in possesion after capturing the area. and it was not a private property. those days rulers also not occupied personal properties without making payments or other land with compensation of the damage. during the times of construction a haveli of a hindu rajah in the ministry of shahjehan got compensation and land for the part of land he gave for taj. historically proved many such occassions. in british times many baghs or gardens were transferred to colleges and schools.so due to calamites and losses by nature many important places lost their existance and records. many facts and technologies finished, and we are away from facts. the only record is old manuscripts,literature,and memoirs remembered by generations. so for another old technology i will tell abot stone bridge which floated to attack ceylon or shrilanka. the stone used was pumic stone which is very light and floats, it was tied on edges by ropes from one end to another .a light bridge which cold not last due to damage of rope after some times in water. the pumic stone is whichnow used to clean at homes. very light and also strong seeto it
