Hipparchus and Surya Siddhanta (21600 and Siderial Zodiac)

[Guest guest]

Dear All,

* Hipparchus (BC 160; Born in Turky, lived in Rhodes in Greece,

possibly made many star observations from Phoenicia in Lebanon) considered the

the Zodiac Circle to be composed of 21600 min.

* Hipparchus used a fixed Sidereal Zodiac (with a fixed

starting point) like the Ancient Indians and NOT the tropical zodiac.

===>

( http://en.wikipedia.org/wiki/Hipparchus )

Hipparchus .............. tabulated values for the chord function, which gives the length of the

chord for each angle. He did this for a circle with a circumference of 21600

and a radius (rounded) of 3438 units: this circle has a unit length of 1 arc

minute along its perimeter

<===

* Some assume that the Surya Siddhanta concept of 21600 Prana

constituting the zodiac circle is an adoption of this Hipparchian concept!!

===>

( http://en.wikipedia.org/wiki/Hipparchus )

He described the chord table in a work, now lost, called Toon en kuklooi

eutheioon (Of Lines Inside a Circle) by Theon of Alexandria (4th century) in his

commentary on the Almagest I.10; some claim his table may have

survived in astronomical treatises in India, for instance

the Surya Siddhanta. Trigonometry was a

significant innovation, because it allowed Greek astronomers to solve any

triangle, and made it possible to make quantitative astronomical models and

predictions using their preferred geometric techniques.

<==

* The surya Siddhanta equates Prana as one of the base unit of

time and considers 21600 Prana (breaths) as the day of a human being and

also that 21600 minutes constituting the Zodiac circle. Brahmanda

Pindanda correlation and Prana kalana (counting of breath) forms the base of

Surya Siddhantic concepts.

* Surya Siddhanta also uses a Siderial Zodiac with a fixed

starting point which starts at Meshadi/Aswinyadi.

* Both Surya Siddhanta and Hipparchus used Polar coordinates, but Ptolemy

dropped the use of Polar coordinates and started used equatorial

coordinates. Indian astronomy based on the Surya Siddhanta tradition flourished

by the use of Polar coordinates (Dhruvanka), which even today traditional

astrologers use for calculation.

 

What do you think?

* Do you think that Ptolemy who never adopted/used/followed the Sidereal

Zodiac and corrupted the star catalogue of Hipparchus as the continuing tradition

of Hipparchus?

* Do you think that Ptolemy of AD 200 who dropped the use of Polar

coordinates (Dhruvanka in Sanskrit) truly understood the methodology and

philosophical background and concepts of Hipparchus? (Even Ptolemy's PI value

was less accurate than Hipparchus's)

* Do you think Hipparchus learned/adopted astrology from Indian

Surya Siddhantic Tradition, or do you think that he might have learned

astrology from Babylonian, or some Phoenician tradition? (Phoenician = Panis;

they are mentioned even in Vedas. They were non-vedic)

* Do you think that Surya Siddhanta borrowed all its philosophy of

Prana, Yoga, Breath-Zodiac correlation (Brahmanda-Pindanda correlation), Mathematical

perfection etc all from Hipparchus?

* Do you think that Hipparchus borrowed from Surya Siddhanta or

Surya Siddhanta borrowed from Hipparchus or that both the knowledge came from

some common tradition such as that of Meluhan (Mleccha) tradition of Sinddhu

Sarasvati or the Phoenician (Pani) tradition?

Just sharing some thoughts.

Love and regards,
