Elias Lönnrot signs and dates the foreword to the first version of the Kalevala, the so-called Old Kalevala.

Elias Lönnrot was a Finnish polymath, physician, philosopher, poet, musician, linguist, journalist, philologist and collector of traditional Finnish oral poetry. He is best known for synthesizing the Finnish national epic, Kalevala from short ballads and lyric poems he gathered from Finnish oral tradition during several field expeditions in Finland, Russian Karelia, the Kola Peninsula and Baltic countries. In botany, he is remembered as the author of the 1860 Flora Fennica, the first scientific text written in Finnish rather than in Latin.
