Carl Christian Constantin Hansen (Constantin Hansen) (3 November 1804 – 29 March 1880) was one of the painters associated with the Golden Age of Danish Painting. He was deeply interested in literature and mythology, and inspired by art historian Niels Laurits Høyen, he tried to recreate a national historical painting based on Norse mythology. He painted also many altarpieces and portraits, including the monumental oil painting The Danish Constituent Assembly (Den grundlovgivende Rigsforsamling) between 1861 and 1865.
