At the moment, this page has one sample of Finnish written in tengwar using the mode described in Suomen kirjoittaminen tengwarilla / Writing Finnish in Tengwar.
The text is the beginning of a reconstructed form of the folk poem "The Death of Bishop Henrik". It begins "Kaksi on pyhä'ä miestä, kaksi kansan ruhtinasta: toinen kasvoi Kaalimaassa, toinen Ruotsissa yleni" - "There are two holy men, two lords of the people: one grew up in Cabbageland, the other in Sweden". The text of the poem is from Martti Haavio: Kirjokansi, and the note in the bottom margin is also derived from that source.
