In valid historical and literary texts, where many of the Semitic prophets have been historically identified with the kings and heroes of Iran's contemporary national history, there is no trace of Christ's name among the prophets compared; whereas considering the integration of Christ's personality and fate with a diversity of fictional elements and motifs (such as mythological, epical and folkloric ones) - which naturally pave the way appropriately for such mentioned identification- is contemplative. Through a survey of historical fictional narratives related to Christ, and comparing it with the mythological, epical and folkloric news about Siavash and Keikhosorw in the Iranian sources, sixteen partial and general identifications are observed between Christ and Siavash; in addition to twenty noticeable other similarities between Christ and Keikhosrow which are quite interesting regarding their types and number. This research has surveyed each instance thoroughly and clarified it, finally concluding that most probably the most common and most comparative personalities in the Semitic narratives and the Iranian narratives are Christ, Siavash and keikhosrow. That is, it seems that the life and features of these three have been discussed through a unique pattern, and according to their characteristics, their commonthemes and motifs are discussed.
