Sohrab and Rustum, epic poem in blank verse by Matthew Arnold, published in 1853 in his collection Poems. Among Arnold’s sources for this heroic romance set in ancient Persia were translations of an epic by the Persian poet Ferdowsī and Sir John Malcolm’s History of Persia (1815). The poem is an account of Sohrab’s search for his father, who disappeared years earlier. A warrior for the Tartars, Sohrab engages in battle with Persian forces. Not realizing that Rustum, the Persian chieftain, is his father, Sohrab challenges the older man in single combat. Source: britannica.com
