Nowadays, short story is the most important literary genre after the poetry, and has extensively spread among the people and in some countries, especially developed ones its frequency is more than others. Short story, as a technical story, has elements like plot, pattern, character, speech, crisis, time, setting, view point, and theme. All these elements move harmoniously and in an organized way around the theme. Persian short story was created by Seyyed Mohammad Ali Jamalzadeh, though we can see its manifestations and revolution in the works of Zeinolabedin Maraghei, Mirza Abdorrahim Taleb of and Mirza Ali Akbar Khan Dehkhoda. 'The Once upon a Time' was written in a literary movement whose origin thoroughly lies in the 19th century. 'Farsi is mellifluous' is the first collection of 'Once upon a time' which has basic difference from Persian traditional stories in which story elements have entered its texture. Of course, there are some criticizing about their thorough and useful enterance.
