only the first three floors and the rose window completed. Architect Helge Thiis In 1929, a new architectural competition was held, and the proposal that won, Kongespeilet was prepared by Helge Thiis. This started the last phase in the restoration of the west front. Thiis was appointed as the cathedral architect, a position he held from 1930 until his death in 1972. He believed that the work on the west front was essentially an artistic exercise in the spirit and form of Gothic architecture and of the Church as a whole, than a reconstruction. His work has much in common with Nordhagen's approved sketch, and represents the west front as it appears today. Construction This concluded that the front should be built following a rhythmic proportional system: "The seated statues have the same height as the first pictorial series, the deep niches as second pictorial series, and in height from cornice band under the royal floor up to the tip of the arch is equal to twice the lower height." The rectangular screen fronts baseline dimensions are based on the principle of the golden ratio. The two columns on each side of the rose window are placed according to this principle, the same is the position of the horizontal delineations between the second and third and between the third and fourth alcove openings. These lines are most clearly visible on the side towers. The rectangular baseline also provides the baseline of an equilateral triangle with a vertex in the west gable front, which was completed in 1963. The rose window forms a circle in the triangle. A circle in an equilateral triangle is often regarded as the symbol for "God's eye." The rose window None of the Nidaros Cathedral's original stained glass windows were intact when the restoration work started in 1869. The concept followed was to reconstruct the church in the Gothic style, and as a result the new stained glass windows should also have standard medieval themes. In 1907 the architect Gabriel Kielland (1871–1960) won a competition for new paintings for Nidaros Cathedral's southern gable. In addition Kielland delivered proposals to all of the church windows, and received the commission to create the stained glass windows. The paintings are iconographic imagery which were produced in collaboration with Oluf Kolsrud (1885–1945), professor of church history. The themes are from the Bible stories and Saint's legends, the windows on the
