Rubáiyát of Omar Khayyám is the title that Edward FitzGerald gave to his 1859 translation from Persian to English of a selection of quatrains (rubāʿiyāt) attributed to Omar Khayyam (1048–1131), dubbed “the Astronomer-Poet of Persia”.
“Last night, my heart was filled with joy, intoxicated by delight.
Yet this morning, upon waking, all that remains is desolation.
How strange it is, in the span of just one night, my heart has become two different souls.”
