The zero degree prime meridian would have been known today as the Avanti meridian. Just like it was intended by the people who invented celestial navigation- Indian astronomers.
Europe acquired this ability from India only in the 16-17th centuries- triggering the colonial waves.
To find your way at sea with the sky as your guide, you need to know your latitude, longitude & loxodrome. THAT requires accurate trigonometric tables.
Which was the only place such tables were found?
Kerala where Madhava used calculus to obtain them.
Correct to 9 decimals!
Who published those EXACT SAME trigonometric values under his own shameless name in 1607?
Christopher Clavius
How did he obtain them?He didn't know calculus!
Jyestadeva's disciple Sankara Variyer(authored Yuktidipika) as well as the Portuguese Jesuits met under the Raja of Cochin
