Varāhamihira

Varāhamihira (c. 505 – c. 587),[1] also called Varāha or Mihira, was an ancient Indian astrologer, astronomer, and polymath who lived in Ujjain (Madhya Pradesh, India). He was born at Kayatha,[2] in the Avanti region, roughly corresponding to modern-day Malwa (part of Madhya Pradesh, India), to Adityadasa. According to one of his own works, he was educated at Kapitthaka.[3] The Indian tradition believes him to be one of the "Nine Jewels" (Navaratnas) of the court of ruler Yashodharman Vikramaditya of Malwa.[4][5] However, this claim appears for the first time in a much later text and scholars consider this claim to be doubtful because neither Varahamihira and Vikramaditya lived in the same century nor did Varahamihira live in the same century as some of the other names in the "nine jewels" list such as the much older Kalidasa.[6]

Varahamihira wrote the Brihat samhita, an influential encyclopedic text in Sanskrit. This text exists in many Indian scripts, and was copied, preserved in Hindu, Jain and Buddhist temples and monasteries.

Varāhamihira's most notable works were the Brihat Samhita, an encyclopedic[7] work on architecture, temples, planetary motions, eclipses, timekeeping, astrology, seasons, cloud formation, rainfall, agriculture, mathematics, gemology, perfumes and many other topics.[8][9][10] According to Varahamihira, in some verses he was merely summarizing earlier existing literature on astronomy, Shilpa Sastra and temple architecture, yet his presentation of different theories and models of design are among the earliest texts that have survived.[11][12] The chapters of the Brihat Samhita and verses of Varahamihira were quoted by the Persian traveler and scholar Al Biruni.[13]

Varāhamihira is also credited with writing several authoritative texts on astronomy and astrology. He learned the Greek language, and praised the Greeks (Yavanas) in his text for being "well trained in the sciences", though impure in ritual order.[14] Some scholars consider him to be the strong candidate as the one who understood and introduced the zodiac signs, predictive calculations for auspicious ceremonies and astrological computations.[15][16][17]

WorksEdit

Pancha-SiddhantikaEdit

Varahamihira's main work is the book Pañcasiddhāntikā ("[Treatise] on the Five [Astronomical] Canons") dated ca. 575 CE, which gives 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 by five authors, namely the Surya Siddhanta, Romaka Siddhanta, Paulisa Siddhanta, Vasishtha Siddhanta and Paitamaha Siddhanta. It is a compendium of Vedanga Jyotisha as well as Hellenistic astronomy (withGreek, Egyptian and Roman elements).[a] Varahamihira was the first one to mention that the Ayanāṃśa, or the shifting of the equinox, is 50.32 arc seconds per year.

They [the Indians] have 5 Siddhāntas:
  • Sūrya-Siddhānta, the siddhānta of the Sun, thought to be composed by Lāṭadeva, but actually composed by Mayasura also known as Mamuni Mayan as stated in the text itself.
  • Vasishtha-siddhānta, so called from one of the stars of the Great Bear, composed by Vishnucandra,
  • Paulisa-siddhānta, so called from Paulisa, the Greek, from the city of Saintra, which is supposed to be Alexandria, composed by Paulisa.
  • Romaka-siddhānta, so called from the Rūm, ie. the subjects of the Roman Empire, composed by Śrīsheṇa.
  • Paitahama-siddhānta.

Brihat-SamhitaEdit

Another important contribution of Varahamihira is the encyclopedic Brihat-Samhita. Although the book is mostly about divination, it also includes a wide range of subjects other than divination. It covers wide-ranging subjects of human interest, including astronomy, planetary movements, eclipses, rainfall, clouds, architecture, growth of crops, manufacture of perfume, matrimony and domestic relations. The volume expounds on gemstone evaluation criterion found in the Garuda Purana, and elaborates on the sacred Nine Pearls from the same text. It contains 106 chapters and is known as the "great compilation".

On AstrologyEdit

 
Varahamihira's Brihajjataka is a Sanskrit text on predictive astrology based on the Vedic Astrology system. The above manuscript was copied in Nepal in 1399 CE in the Nepalaksara script, and is now in the Cambridge University Library.

Hora Shastra or Brihadjathaka is a most acclaimed astrological work by Mihira. It is mostly in code language. More than a dozen commentaries have been written for this work. The Kerala School of Astrology is mainly based on the Brihadjathaka.

His son Prithuyasas also contributed to Hindu astrology; his book Hora Sara is a famous book on horoscopy. Khana (also named Lilavati elsewhere), the medieval Bengali poet astrologer, is believed to be the daughter-in-law of Varahamihira.

ContributionsEdit

TrigonometryEdit

Varahamihira improved the accuracy of the sine tables of Aryabhata.

CombinatoricsEdit

He also records the first known 4×4 magic square[citation needed].

OpticsEdit

Among Varahamihira's contribution to physics is his statement that reflection is caused by the back-scattering of particles and refraction (the change of direction of a light ray as it moves from one medium into another) by the ability of the particles to penetrate inner spaces of the material, much like fluids that move through porous objects.[19]

NotesEdit

  1. ^ The Pañca-siddhāntikā ("Five Treatises"), a compendium of Greek, Egyptian, Roman and Indian astronomy. Varāhamihira's knowledge of Western astronomy was thorough. In 5 sections, his monumental work progresses through native Indian astronomy and culminates in 2 treatises on Western astronomy, showing calculations based on Greek and Alexandrian reckoning and even giving complete Ptolemaic mathematical charts and tables.[18]
