Itihas (Sanskrit: Itihās, "historical event"; from iti, ha and ās, lit. "so indeed it was") as defined by Amarakosha (I.6.4) refers to purvavritta, i.e. events of the past. In the Vedic age, those portions of the Brahmanas which narrated events of bygone days were known as itihasa and had some ritualistic importance. The recitation of the itihasa-purana in the pariplava nights was a part of the Asvamedha ritual.[1] Later, the connotation of the term widened to cover all such narratives which related to past events – partly facts and partly myths.
