OMAR KHAYYAM: HOW THE POET AND ASTRONOMER CHANGED THE WAY PEOPLE MEASURE TIME "[In] the Persian city of Isfahan, Khayyam worked in an observatory where he eventually succeeded in precisely measuring the length of the year, leading to the development of the new Jalali calendar.... based on the sun's movement, as well as quadrennial and quinquennial leap years.... In the West, however, it is Khayyam’s work as a poet and his collection of quatrains that is recognised and celebrated...translated by Edward FitzGerald in the 1800’s and published in The Rubáiyát of Omar Khayyám." via THE INDEPENDENT |
