The Golden Age of Finnish Art coincided with the national awakening of Finland, during the era of the Grand Duchy of Finland under the Russian Empire. It is believed to span an era from the late 19th Century to the early 20th Century, approximately 1880 to 1910. The epic poetry form known as Kalevala, developed during the 19th Century, provided the artistic inspiration for numerous themes at the time, including in visual arts, literature, music and architecture; however, the "Golden Age of Finnish Art" is generally regarded as referring to the realist and romantic nationalist painters of the time. Notable figures of the time include Akseli Gallen-Kallela, Pekka Halonen, Albert Edelfelt, Jean Sibelius, Eino Leino, Helene Schjerfbeck, Emil Wikström, Eero Järnefelt and Eliel Saarinen.
