"From Visualization of Polyhedra to Art about Mathematics"

Every artist has his own story that he tries to tell throughout his work. My story is about my fascination about mathematics. In history we see that artist were invited to illustrate mathematical books. A well-known example is the drawings that Leonardo da Vinci made for the book Divina Proportione written by the mathematician Luca Pacioli. And Albrecht Dürer made polyhedron drawings for his own book "Underweysung der Messung, mit dem Zirckel und Richtscheyt, in Linien, Ebenen unnd gantzen corporen". In their work mathematical ideas become visual. It is important to state that Leonardo da Vinci and Albrecht Dürer both where artists, artists fascinated by mathematics. Later on we see in the works of M.C. Escher, that he tries to visualize complex polyhedra in a clear way. But his works are not mathematical illustrations anymore, but real works of art. He took mathematical objects as subject for his art. Inspired by M.C. Escher and also Leonardo da Vinci and Albrecht Dürer, I started to develop my own way of creating art. And now again: Art about Mathematics. In my lecture I will show and explain about my sculptural work, as well as how the mentioned artists have inspired me.


Swantje Wittenhagen, harp

Hamburg harpist Swantje Wittenhagen (*1999) began playing the harp at the age of five with Sabine Fichner. At the age of nine, she switched to Prof. Gesine Dreyer, with whom she initially took private lessons, and from 2013 as a junior student via the Lübeck University of Music. After graduating from high school in 2017, Swantje began her bachelor's studies in harp at the University of Art in Graz with Prof. Margit-Anna Süß. She returned to Lübeck in October 2018 and completed her Bachelor's degree with Gesine Dreyer in the summer of 2021. Swantje Wittenhagen is a multiple first prize winner of the competition "Jugend musiziert", as well as winner of "Wespe" in the categories "Verfemte Musik" and "Werk einer Komponistin". In addition, she was third in the International Harp Competition of Hungary. In 2019, she won the Possehl Music Competition of the University of Music Lübeck. She has been playing as an orchestral harpist since she was eight years old and was most recently a harpist with the German Federal Youth Orchestra, the Schleswig Holstein Music Festival Orchestra, and the European Union Youth Orchestra (EUYO). In the 2019/20 season, she was an academist with the Lübeck Philharmonic Orchestra. From the 2021/22 season, she will be part of the Gürzenich Orchestra Cologne as an academist for the next two years. Swantje Wittenhagen was a scholarship holder of the Förderverein "Jugend Musiziert", as well as of several master classes. For several years she has been a scholarship holder of the "Deutsche Stiftung Musikleben". She received the Gerd Bucerius Scholarship of the foundation, as well as several sponsorship scholarships, which were made possible by the Bernbeck Foundation and the Dr. Werner and Hilke Appel Foundation. From 2019-2021, Swantje was a fellow of the Possehl Foundation Lübeck. In 2021, she received a sponsorship scholarship from the Hans and Eugenia Jütting Foundation.
