"The Kalevala is considered the national epic of Finland. It was compiled and edited by Elias Lönnrot while he was a district health officer in eastern Finland, at that time under the governance of Russia. The poem consists of 50 runos or cantos and 22,795 lines of poetry. The poem tells the story of a people, from the very beginning of the world to the introduction of Christianity."

The two volume version on Project Gutenberg seems to be a better translation. Volume I consists of runos 1 through 25. Volume II consists of runos 26 through 50. Both volumes are close to 300 pages each. The first volume is probably a good place to start for next month. We can continue on to the second volume in the future.
