Frederik Macody Lund

Julius Frederik Macody Lund (born 18 November 1863 – 16 December 1943) was a controversial Norwegian autodidact revisionist historian, most known and remembered for his engagement in the restoration of Nidaros Cathedral.

When architect Christian Christie presented his ideas for a restoration of the west section and the west front,[clarification needed] an alternative idea was published by Macody Lund, introducing the screenfront and the rose window.

In 1915 Macody Lund published his theory that Nidaros Cathedral was constructed on the basis of the ideas of the golden ratio.

The dispute was settled in 1922, when an international experts commission rejected Macody Lund's theories.

Macody Lund thus saw an opportunity to continue his argument, which he published in Ad Quadratum II: Dom med præmisser over den internasjonale domskommissions dom uten præmisser (1928) ("A verdict with premises on the international experts commission's verdict without premises").
