"Tursas" (derrived from the Finnish word "tursaansydän"), Tursas being a creature from Finnish mythology mentioned several times in Kalevala. Two of his variant Finish names: 'Iku-Turso' (the eternal octopus)and 'Meritursas' (ink fish/octopus) reflect its general nature of being an altogether malevolent and violent sea monster. Finnish mythology also attributes him as a father of diseases, who could spit deadly projectiles of his filth and pestilence. According to varying sources, Tursas may or may not have been associated as a god of war.
The Heart of Tursas / tursaansydän is an ancient symbol of good fortune and meant to repel curses and other vexations. It dates back to prehistoric times and generally takes the shape of four overlapping symbols (commonly four arrows or four squares), which create a swastika within its center.
