Persian polymath, scholar, mathematician, astronomer, philosopher, and poet, widely considered to be one of the most influential thinkers of the Middle Ages. He also wrote numerous treatises on mechanics, geography, mineralogy, astronomy and music. His one long poem, "The Rubiyat," brought him lasting fame. He composed more than 750 four-line verses. As royal astronomer, he changed the Persian calendar, and also wrote an Arabic book on algebra.

At a young age he moved to Samarkand and obtained his education there. Afterwards he moved to Bukhara and became established as one of the major mathematicians and astronomers of the Islamic Golden Age. He wrote one of the most important treatises on algebra written before modern times, the Treatise on Demonstration of Problems of Algebra (1070) which includes a geometric method for solving cubic equations by intersecting a hyperbola with a circle. He contributed to a calendar reform.

His significance as a philosopher and teacher, and his few remaining philosophical works, have not received the same attention as his scientific and poetic writings. He taught the philosophy of Avicenna for decades in Nishapur.

Outside Iran and Persian-speaking countries, Khayyám has influenced literature and societies through the translation of his works and popularization by other scholars. The greatest such effect was in English-speaking countries. The English scholar Thomas Hyde (1636–1703) was the first non-Persian known to have studied his works. The most influential, however, was Edward FitzGerald (1809–1883), who made Khayyám famous in the West through his translation and adaptations of Khayyám's quatrains in the Rubaiyat of Omar Khayyam.

Khayyám died on 4 December 1131 OS, aged 83, and is buried in the Khayyám Garden in Nishapur. The reconstruction of the tombs of Persian icons like Hafez, Saadi, Attar, Pour Sina and others were built by Reza Shah and in 1963, the Mausoleum of Omar Khayyám was reconstructed on the site by Hooshang Seyhoun.

Source Notes

Sy Scholfield quotes from In Search of Omar Khayyam (RLE Iran B) by Ali Dashti (1971; Taylor & Francis, 2012), p. 11: "His date of birth, long a matter for speculation, seems finally to have been determined by the Indian scholar, Swami Govinda Tirtha [in The Nectar of Grace: ʻOmar Khayyām's Life and Works, Kitabistan, 1941], who was the first to realize that the astrological information given by his earliest biographer, Beihaqi, and dismissed by serious scholars as unworthy of their attention, was, if genuine, sufficient to establish the date with extreme precision, that is to say, 'at sunrise on 18 May 1048', a date that incidentally satisfies all other requirements." Scholfield calculates Sun on the ascendant at 4:51 AM LMT. Arthur Blackwell previously gave same data (with time of 4:50 AM; details below) probably from same such source, and Blackwell is thus credited as collector. (This chart gives ascendant and Sun both in third degree of Gemini and Venus and Mercury in the sixth and seventh degrees of Gemini).

Previously this entry had "21 May 1048 at 04:41 (= 04:41 AM) jul." (This chart gives ascendant and Venus both in the fourth degree of Gemini and Mercury and Sun in the fifth and sixth degrees of Gemini). This previous entry had the following source notes:

Various source Notes: Juan Revilla gave a reference from a book by L.P. Elwell-Sutton, "The Horoscope of Asadullah Mirza", Leiden, 1977, page 3, where there is quote of a book written by a certain Baihaqi, called "Tatimma Siwan al-Hikma," stating that "His Ascendant was Gemini. The Sun and Mercury were on the degree of the Ascendant in the third degree of Gemini. Mercury was Cazimi and Jupiter was in trine with both."

Revilla writes, "This short quote allowed scholars to date exactly Khayyam's horoscope: May 21, 1048. Elwell-Sutton explains that the source of the quote is E. Denison Ross and H.A.R. Gibb, "The Earliest Account of "Umar Khayyam" (B.S.O.S., v, 1928-30, p.471) (I don't know what the initials mean, this is how it appears in Elwell-Sutton's book). They had discarded it as supplementary astronomical data, and it was Swami Govinda Tirtha (in "The Nectar of Grace, Allahabad, 1941, pp.xxxii-xli) the first to note that the quote contained in it the exact date and time, unknown until then.

Revilla continues, Baihaqi was one of the greatest classical writers of Persian prose literature of the Seljuq Era, i.e., the same era in which Omar Khayyam lived. His "History of the Gaznavids" is called "one of the four great masterpieces of early Persian prose", so we can safely assume that he was a contemporary of Omar Khayyam, and very possibly had Khayyam's horoscope in front of him. His testimony on the horoscope of Omar Khayyam has authority and has been widely accepted by modern scholars, after it was shown by Swami Govinda Tirtha in 1941 (the book mentioned) that the testimony contained implicitly the exact date of his birth.

"Done with modern standards (Khayyam was born in Naishapur in Khorassan), the conjunction is less exact, but Mercury appears in exact conjunction with Venus, compensating the excess of intellect. From his poetry, one can guess that the date is probably the 19th, with the Moon in Cancer and not in Gemini. [ref. "ACT" mailing list, 1 July 2000]

(Formerly, Arthur Blackwell gave May 18,1048 OS, (May 24 NS), 4:50 AM LMT, source unknown.

Van Norstrand in AJA Spring/1937, "From the chart I have, the astrologer supposed he was born a few minutes after sunset, July 20, 1050 OS, July 25 NS, Khorassan, Persia, 58 E.00, 35 N.00."

Fagan in AQ Spring/1937 stated that July 25, 1050 was OS and July 31, NS. In AA April/1940 he asks Van Norstrand for his historical source and validation. Response not on record.

Penfield Collection gives May 18, 1048 OS, 4:18 AM LMT, Nishapur "from an old book on Hindu astrology."

World Book Encyclopedia gives "?", Americana Encyclopedia gives "about 1132.")
