Ferdowsi's competence and skillfulness, in previous centuries, on the numerous types of techniques of story writing and his witty sayings which have recently been discovered by the critics, are amazing, one of which is "the center of narration in the Shahnameh". It has great importance in the analysis of potencies which the storyteller has utilized to give form to his stories so far that making any modification in the center of the narration causes distinction and change in the main stream of the story and even its topics. The diversification of vision centers and the different forms of the narrator's communication with what makes the center and angle of the view in the Shahnameh is so appealing and conscious that its analysis can show corners of Ferdowsi's genius in a work which is beyond time and place. Ferdowsi's other skillfulness in telling the stories is the way in which he uses "the time element" in the narration. One of the researchers who, in the recent decades, used the chronology in telling stories was Janet from France who propounded three discussions of "regularity, continuity, and frequency" and fame in this domain. It is tried, in this essay, to investigate the different kinds of view points in reliance on Rostam and Esfandiar and, based on Janet's theory, to show how ferdowsi used the element of time in his story and as a story-teller used the calendar of time, and how he dealt with the different choices and their direct and meaningful relations with the theme of the story.
