Although the only surviving work by Firdusi (fur-DEW-see) is the Sah-name, another long poem titled Yusuf u Zulaikha (Joseph and Zulaikha), detailing the story of the biblical character Joseph and Potiphar’s wife, has been attributed to Firdusi. This poem, however, is not Firdusi’s and belongs to a much later period. Other verses scattered in various anthologies of the classical period have been ascribed to the poet, but none of these fragments can be assigned to him with certainty. These fragments have been collected and studied by H. Ethé in his Firdûsî als Lyriker (1872-1873).
