I want to know the answer to the following question:
How did the translation of Rubaiyat achieve an Oriental flavor?
All the background I'm provided with is that "An exception was the outstanding translation in this period, Edward FitzGerald's Rubaiyat of Omar Khayyam (1859), which achieved its Oriental flavor largely by using Persian names and discreet Biblical echoes and actually drew little of its material from the Persian original.". Is that enough to answer the question?
Answer: yes
