Lönnrot, Elias (ĕlēˈäs lönˈrōt) [key], 1802–84, Finnish philologist, compiler of the Kalevala. Although he was trained as a physician, he spent his life, after 1828, traveling through Finland, Lapland, and NW Russia, collecting fragments of the Kalevala from the rune singers. Of these he published in 1835 about 12,000 lines. A second edition of nearly 23,000 lines appeared in 1849. To Lönnrot must go the credit of creating a national epic from the scattered fragments sung or recited.
