...12.55. Parallel and Right spheres...85
...Starry sphere -right to left and left to right for [asura]...85
...At equator always east to west -same night and day length...85
The complete contents of the book is given below.
The most significant features of the document are
1. The acknowledgement that an [asura] called [maya] imparted the knowledge of "astronomy" to Hindus that worship [deva].
2. The [asura] were residents of the "nether world" which is opposite side the world of the [deva].
3. There are mentions of northern and southern hemispheres and that there is no up and down for the globe.
The ancient civilizations of the world can generically classified as th Northern civilizations of which Hindu and India is a part. History tells us that Americas were discovered recently. And in the South and Meso America were great ancient civilizations of the Maya. Geographically the Hindu civilization and India are more orless diametrically opposite sides of the globe.
Comparative study of the two well known ancient civiizations however practically non existent. And there is need for diligent study.... (the author)
