Rubaiyat，the quatrains written by the ancient Persian poet Omar Khayyam，has become a gem of English literature after being creatively translated by the British poet Edward FitzGerald in 1859． Its various Chinese translation versions have also aroused intensive attention，among which the most praised one was made by a physics professor of MIT: Kerson Huang． Ironically，both FitzGerald’s and Huang’s translations are well known for their unfaithfulness to the originals． Through the analysis of their translations，this paper points out that imitation method，half translation plus half writing on the basis of intertextuality，is an effective way to translate poetry．
