In this paper, I identify and analyse regular geometric forms that appear in nineteenth-century Finnish author Aleksis Kivi’s texts. His characters and his narrators exemplify these forms to the reader. The characters’ environments are geometrically described, mapped and constructed in Seven Brothers, and geometric figures also exist in several of Kivi’s novels, plays and poems. Circles are the most common of these figures. Thus, I concentrate on expanding and converging regular geometric forms that connect to circles.
