The short recurve was in use in Hungary and some Asiatic cultures, I believe. Do you have any info on historical archery in Finland?
First of all I would like point to my other thread at
PaleoPlanet as it contains much more information about the topic I'm going to discuss now.
Finns or any other nation at Fennoscandia did not use short recurves but all of the illustrations I'm aware drew their inspiration from outside the area. There are no complete indigenous bows preserved in Fennoscandia, save for one late-18th century Saami bow in Sweden. However based on written and linguistic sources from 16th to 19th century I'm positive that Finns used the same type of bow as Saami and other Finno-Ugric nations in Eastern Europe and Siberia. There are also some parts of bows preserved in bogs to back up this theory.
This type of bow is usually laminated from birch and pine which has sufficient amount of
compression wood in it. However individual authors mention also combinations birch-willow and birch-spruce. The glue used in the joints was probably made from fishes, antlers or in one case from pine pitch. Birch bark was wrapped around the bow to protect it from moisture. These bows were taller than the users; measurements from very similar Siberian bows show that they were usually between 170-190 centimeters in length. These bows were abandoned in favour of crossbow during 17th and 18th centuries which was in turn switched to firearms during the 19th and 20th centuries.
Other type of bow used in Finland we are know of is the self bow. This was probably used the Mesolithic era when the temperatures were high enough to allow oaks and maples to grow in Finland in sufficient numbers, but also during Middle Ages due of possibly Swedish influence.
