The Kalevala

The Kalevala is a Finnish national epic compiled by Elias Lonnrot from oral folk poetry he collected himself from rural singers, first published in 1849, so it sits between a primary oral tradition and one compiler's editorial arrangement of it into a continuous narrative. Its strength as a source is that it preserves genuine traditional Finnish mythological material that might otherwise have been lost, gathered directly from oral performers rather than invented. Its limit is that Lonnrot actively edited, combined and arranged separate songs from different singers and regions into a single continuous story, a compiling choice scholars have long noted shapes the narrative more than any one original singer's performance did, so it should be read as a compiled epic rather than a single unaltered ancient text.
