In 1958, Odysseas Mesaritakis from Sivas at Pirgiotissa Province invented a carnival appearance that soon became the carnival trademark of Sivas. The mask of Sivas, made of the root of the local plant athanatus, and adorned with goat horns and other objects, caused the fear of the little kids at carnivals, and mothers mentioned this to make the children eat all their food!
The Sivan mask was very popular in the 1960-70 but soon was forgotten, despite the individual efforts of some residents to make some new. In 2013, after many years, the Cultural Association of Sivas restored this custom and the mask of Sivas reappeared at several carnivals of Messara.
