Hamina 1873-1917 Ahtari, Finnish painter and printmaker. He first studied at the Finnish Fine Arts Association in Helsinki. His natural inclination towards mysticism led him to seek the instruction of Akseli Gallen-Kallela, with whom he studied in Ruovesi intermittently between 1895 and 1897. Gallen-Kallela's influence, in particular his Symbolist synthesis of the National Romantic style, is evident in Simberg's early works, such as Frost and Autumn (both 1895; Helsinki, Athenaeum A. Mus.), which are highly personal expressions of the mysticism of nature.
