It is well-known today that many peoples trace their origin back to a group of people known as the Proto-Indo-Europeans, who probably lived c. 4000 BCE. Among them are some of the most mythologically-rich cultures in the world - most of Europe (including the Greeks and Romans); northern India; and also the Persians.

Much work has been done in reconstructing the shared language of the PIE people; what about their mythology? I am aware of some weak but well-substantiated connections, such as the fact that the Norse Æsir and the Hindu Asuras were probably the same group of beings at one point. Have we managed to reconstruct any narratives that putatively are derived from common PIE myths?
