Philipp Otto Runge was a German artist, draftsman, painter, and color theorist. Runge and Caspar David Friedrich are often regarded as the leading painters of the German Romantic movement. He is frequently compared with William Blake by art historians, although Runge's short ten-year career is not easy to equate to Blake's career. By all accounts he had a brilliant mind and was well versed in the literature and philosophy of his time. He was a prolific letter writer and maintained correspondences and friendships with contemporaries such as Carl Ludwig Heinrich Berger, Caspar David Friedrich, Johann Wolfgang von Goethe, Friedrich Wilhelm Joseph Schelling, Henrik Steffens, and Ludwig Tieck. His paintings are often laden symbolism and allegories. For eight years he planned and refined his seminal project, Tageszeiten, four monumental paintings 50 square meters each, which in turn were only part of a larger collaborative Gesamtkunstwerk that was to include poetry, music, and architecture, but remained unrealized at the time of his death. With it he aspired to abandon the traditional iconography of Christianity in European art and find a new expression for spiritual values through symbolism in landscapes. One historian stated "In Runge's painting we are clearly dealing with the attempt to present contemporary philosophy in art." He wrote an influential volume on color theory in 1808, Sphere of Colors, that was published the same year he died.

Caspar David Friedrich was a German Romantic landscape painter, generally considered the most important German artist of his generation. He is best known for his allegorical landscapes, which typically feature contemplative figures silhouetted against night skies, morning mists, barren trees or Gothic ruins. His primary interest was the contemplation of nature, and his often symbolic and anti-classical work seeks to convey a subjective, emotional response to the natural world. Friedrich's paintings characteristically set a human presence in diminished perspective amid expansive landscapes, reducing the figures to a scale that, according to the art historian Christopher John Murray, directs "the viewer's gaze towards their metaphysical dimension".
