The Song of the Red Ruby (Sangen om den røde rubin, 1956) is a Norwegian novel written by Agnar Mykle. It is a story of the young Ask Burlefot's personal ride through shame and letdowns that eventually leads to a closer and deeper understanding of himself. It was controversial in Norway and other countries at the time of publication and ended in court as the so-called Mykle Case. This controversy was due to the explicit sexual descriptions in the adventures of the potent main character. In Norway, the publisher was acquitted, but for instance in Finland the book was confiscated and burnt.
