INDIA had a prime meridian of its own much ahead of the Greenwich meridian and it was called “madhya rekha”, which passed through the city of Ujjain in Madhya Pradesh, according to a new Class-6 NCERT textbook for social science. No mention of caste-based discrimination, tweaks in references to Dr B R Ambedkar’s experience about the discrimination, referring to the Harappan civilisation as “SindhuSarasvati” are also among the changes in the textbook developed according to a new curriculum. “The Greenwich Meridian is not the first prime meridian. There were others in the past. In fact, many centuries before Europe, India had a prime meridian of its own! It was called madhya rekha (or ‘middle line’) and passed through the city of Ujjayini (todayUjjain),which was a reputed centre for astronomy over many centuries. “Varahamihira, a famous astronomer, lived andworked theresome1,500 years ago.

 

Indian astronomers were aware of the concepts of latitude and longitude,including theneed for a zero or prime meridian. The Ujjayini meridian became a reference for calculations in all Indian astronomical texts,” the textbook reads. In a departure from the past, the textbook makes multiple references to the “Sarasvati” riverin the chapter pertaining to the beginningof theIndiancivilisation. In the new textbook, the river findsaprominentplace in a chapter on the “Beginnings of Indian Civilisation”, where the Harappan civilisation is referred to as the “IndusSarasvati” or “SindhuSarasvati”civilisation. It says the“Sarasvati” basinincluded major cities of the civilisation -- Rakhigarhi and Ganweriwala -- along with smallera cities and towns. The river, according to the new textbook,“today goesby thenameof‘Ghaggar’in India and ‘Hakra’ in Pakistan (hence the name ‘GhaggarHakra River’)” and is now seasonal.The textbook, titled “ExploringSocietyIndia and Beyond”, has details on the Vedas without mentioning the caste system and that women and Shudras were not allowed to study these scriptures.

 

According to the newbook,“Manyprofessions are mentioned in the vedic texts, such as agriculturist, weaver, potter, builder, carpenter, healer, dancer, barber, priest, etc.” The previous textbook said, “Some priests divided people into four groups called varnas.... Shudras could not perform any rituals. Often women were grouped with Shudras. Both women and Shudras were not allowed to study the Vedas.” “The priests also said that these groups were decided based on birth.For example, if one’s father and mother were Brahmins, one would automatically become a Brahmin and so on...,” the old book said.
