Ram
Yantra, as it represents by its name, is an instrument, which is very helphul to the
astronomers to find out the zenith distance and the altitude of the sun. The beauty of the
instrument is, that it givs us direct readings. Basically the instrument consists of two
circular stone building. If we unite them together, it becomes one instrument. This way
one is complimentary to the other. They are constructed at a resonable distance. In the
center of the instrument a prependicular rod is fixed, which is of the same height of the
building itself.
Twelve stone triangles are
fixed above the ground. These triangular stone slabs are graduated from 90 degree to 45
degree, while 45 to 0 degree the graduations are on the circular wall. This is an
instrument by which we come to know the movement of stars. |
