Khayyam was born in Nishabur, in northeastern Iran in May 18, 1048. As a mathematician, he is most notable for his work on the classification and solution of cubic equations, where he provided geometric solutions by the intersection of conics. Khayyam also contributed to the understanding of the parallel axiom. As an astronomer, he designed the Jalali calendar, a solar calendar with a very precise 33-year intercalation cycle.

Khayyam is one of the best known Persian poets in world where a lot of English readers are also attracted to his poems. His poetry became widely known to the English-reading world in a translation by Edward FitzGerald, which enjoyed great success in the Orientalism of the fin de siècle.

Yon rising Moon that looks for us again –
How oft hereafter will she wax and wane;
How oft hereafter rising look for us
Through this same Garden – and for one in vain!

Omar Khayyam
