Aromanian language
The community Dovisdana was created in 1919 (Law 184A - August 19), and was renamed Prosilio in 1928 (Law 81A - May 14). The community became a part of the municipality of Tzoumerka and became a municipality district under Law 244A on December 4, 1997. Its inhabitants were not of Aromanian origin, but since they traded mainly with Aromanians, they understood and spoke the Aromanian language.
