Rubaiyat of Omar Khayyam; Translated Into English Quatrains by Edward Fitzgerald -- A Complete Reprint of the First Edition and the Combined Third, Fourth and Fifth Editions, with an Appendix Containing Fitzgerald's Prefaces and Notes

xxii, 149 pp. Illustrated by Mahmoud Sayah with decorative margins. Omar Khayyam, Arabic in full Ghiyāth al-Dīn Abū al-Fatḥ ʿUmar ibn Ibrāhīm al-Nīsābūrī al-Khayyāmī, (born May 18, 1048, Neyshābūr [also spelled Nīshāpūr], Khorāsān [now Iran]—died December 4, 1131, Neyshābūr), Persian mathematician, astronomer, and poet, renowned in his own country and time for his scientific achievements but chiefly known to English-speaking readers through the translation of a collection of his robāʿīyāt (“quatrains”) in The Rubáiyát of Omar Khayyám (1859), by the English writer Edward FitzGerald. His name Khayyam (“Tentmaker”) may have been derived from his father’s trade. He received a good education in the sciences and philosophy in his native Neyshābūr before traveling to Samarkand (now in Uzbekistan), where he completed the algebra treatise, Risālah fiʾl-barāhīn ʿalā masāʾil al-jabr waʾl-muqābalah (“Treatise on Demonstration of Problems of Algebra”), on which his mathematical reputation principally rests. In this treatise he gave a systematic discussion of the solution of cubic equations by means of intersecting conic sections. Perhaps it was in the context of this work that he discovered how to extend Abu al-Wafā’s results on the extraction of cube and fourth roots to the extraction of nth roots of numbers for arbitrary whole numbers n. - Britannica
