Lund Cathedral, the seat of the Archbishop of Lund, was the main cathedral of the Catholic Church in the Nordic countries during the Middle Ages. It was built at the beginning of the 12th century and consecrated to the Virgin Mary and the holy martyr Laurentius. The museum director, Dr. Göran Axel-Nilsson (1907-1999), was a prolific writer on art and cultural history. His most recent works include Thesaurus Cathedralis Lundensis, a book on Lund Cathedral's medieval treasure collection published by Göteborgs Kungl. Vetenskaps- och Vitterhetssamhälles skriftserie 1989. Another work Laurentius, the patron saint of Lund Cathedral - "Sanctus Laurentius Patronus Ecclasiae Lundensis" - was completed before he passed away, but without being able to fully complete it for printing. The work can be seen as a continuation of "Thesaurus" and deals with the medieval bronze sculpture in Lund Cathedral, depicting the saint and martyr Laurentius, which according to the author is in fact a reliquary. St. Lawrence is one of the most famous of depicted martyrs, many churches in Europe are dedicated to him, which are described in the text. Not only the figure of St. Lawrence but also the other medieval bronze objects in the choir of Lund Cathedral are described in detail and photographed in every detail. The essay, after review by the researcher in medieval archaeology Professor Hans Andersson, has been approved by the Royal Society of Science and Letters in Gothenburg for inclusion in its publication series. The project intends to complete Axel-Nilsson's work.
