The long poem is a literary genre including all poetry of considerable length. Though the definition of a long poem is vague and broad and unnecessary, the genre includes some of the most important poetry ever written. With more than 220,000 (100,000 shloka or couplets) verses and about 1.8 million words in total, the Mahābhārata is the longest epic poem in the world. It is roughly ten times the size of the Iliad and Odyssey combined, roughly five times longer than Dante's Divine Comedy, and about four times the size of the Ramayana and Ferdowsi's Shahnameh.
