ريشه مشترك تاريخ اساطيري ايران و ژرمن

The Lay of Hildebrand (Das Hildebrandslied) is a heroic lay, written in Old High German alliterative verse. It is one of the earliest literary works in German, and it tells of the tragic encounter in battle between a son and his unrecognized father. It is the only surviving example in German of a genre which must have been important in the oral literature of the Germanic tribes.

A more distant analogue is the Persian tale of Rostam in the Shahnameh (The Epic of Kings), who kills his son Sohrab in single combat between two armies. They do not recognize each other until, after Sohrab has been fatally wounded, Rostam sees the arm-ring he had given his son at his birth. The similarities with the Hildebrandslied suggest the story may derive from an Proto-Indo-European folk tale.
