The Seven Labors of Rustam (Persian: هفت خان رستم, romanized: Haftkhān-e-Rostam) were a series of acts carried out by the greatest of the Iranian heroes, Rostam, The story was retold by Ferdowsi in his epic poem, Shahnameh. The Seven Labours were seven difficult tasks undertaken by Rostam, accompanied, in most instances, only by his faithful and sagacious steed Rakhsh, although in two labours he was accompanied also by the champion, Olad.
