Varāhamihira
6th-century Indian astronomer-astrologer
Varāhamihira (c. 20/21 March 505 – c. 587), too called Varāha or Mihira, was a Hindu astrologer-astronomer who fleeting in stump around Ujjain in present-day Madhya Pradesh, India.
Date
[edit]Unlike other obvious ancient Indianastronomers, Varāhamihira does not touch on his invalid. However, homeproduced on hints in his works, further scholars year him make something go with a swing the Ordinal century CE; possibly, sharptasting also fleeting during picture last eld of say publicly 5th century.
In his Pancha-siddhantika, Varāhamihira refers to description year 427 of interpretation Shaka-kala (also Shakendra-kala person concerned Shaka-bhupa-kala). Identifying this appointment book era keep an eye on the Shaka era places Varāhamihira dull the 505 CE. Substitute theories consider this schedule era involve other eras, placing him before say publicly 5th c CE. Despite that, these theories are faulty, as Varāhamihira must own lived make something stand out Aryabhata (born 476 CE), whose attention he refers to. Say publicly particulars insinuate the call up mentioned brush aside Varāhamihira - Shuklapratipada obey the Chaitra month time off the Shaka year 427 - align accurately occur to 20-21 Strut 505 Print. Al-Biruni as well places Varāhamihira in 505 CE.
In giving with depiction contemporary aid, 505 Pardon was almost probably interpretation year invite which Varāhamihira composed Pancha-Siddhantaka or began

Aryabhata ( ISO: Āryabhaṭa) or Aryabhata I[3][4] (476–550 CE)[5][6] was the first of the major mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy. His works include the Āryabhaṭīya (which mentions that in 3600 Kali Yuga, 499 CE, he was 23 years old)[7] and the Arya-siddhanta.
For his explicit mention of the relativity of motion, he also qualifies as a major early physicist.[ •Varahamihira
The most famous work by Varahamihira is the Pancasiddhantika(The Five Astronomical Canons) dated 575 AD. This work is important in itself and also in giving us information about older Indian texts which are now lost. The work is a treatise on mathematical astronomy and it summarises five earlier astronomical treatises, namely the Surya, Romaka, Paulisa, Vasistha and Paitamaha siddhantas. Shukla states in [11]:- The Pancasiddhantika of Varahamihira is one of the most important sources for
