In philosophy, in religion, in everyday life - centuries-old wisdom - that measure of cognition of the world, practical experience of human existence in this world. One of its manifestations is winged sayings, they are maxims, they are aphorisms. These brief and succinct phrases are copyright or folk (authorship is lost). In the Iranian or Persian tradition, such aphorisms can have a poetic (lyrical) form, and are called rubyes.

The most famous Persian aphorist is Omar Khayyam Nishapuri (1048-1131) - a Persian mathematician, philosopher and poet. He contributed to algebra by constructing a classification of cubic equations and solving them using conic sections. This method is still used.

The themes of Omar Khayyam’s poetic aphorisms are diverse, from religion, science, politics, to love, sadness, joy and a sense of beauty. But nihilistic notes still prevail in aphorisms - the meaninglessness of being, frailty, etc. Omar Khayyam’s passion for wine and drunkenness and the justification of debauchery stand out. Omar Khayyam is like a bully and shocking. And it looks like another sage - the ancient Greek cynic Diogenes.
