The Walhalla is a neo-classical hall of fame which honours the most important people in German history. It was conceived in 1807 by Ludwig I of Bavaria (king from 1825 to 1848) and its construction took place between 1830 and 1842 designed by Leo von Klenze.
The Walhalla was inaugurated on October 18, 1842 with 96 busts and 64 commemorative plaques for people with no available portrait and everything was presided by the great King Ludwig:
Among all these very famous people related with the German history there are some… of course… mathematicians who share this space with Bach, Göethe, Beethoven, Guttemberg, Luther, Otto von Bismarck,… First of all, Dürervis the great German painter from the Renaissance who applied a lot of perspective new techniques to his paintings:
The great astronomers are also here. Regiomontanus,…
The great Leibniz…
and the greatest Gauss (added in 2007), also have their busts in this hall of fame:
Finally, Albert Einstein’s bust was added in 1990:
I must say that the commemorative plaques also mention Alcuin of York, Albertus Magnus and the Venerable Bede, all ot them related with the wonderful Arithmetics!
Come to Regensburg to see this beautiful (and strange) place!

Nicholas Kratzer was born in Munich and arrived in England in 1516. He became member of the scientific circle around Sir Thomas More (1478-1535) from tutoring More’s children in astronomy and mathematics. After being introduced at Henry VIII’s court (Kratzer was appointed the royal astronomer in 1520), he became friend of important painters as Hans Holbein the Younger and Albrecht Dürer.
In this portrait painted by Holbein, he is surrounded by some astronomical instruments as a sundial or a quadrant and we can see how Kratzer was engraving a polyhedrical sundial.
It’s possible to visit a very interesting exhibition in Madrid about Albert Durer’s engravings in the Biblioteca Nacional of Madrid (from the 6 of February to 5 of May):
I was in the Spanish National Library last March and I had the opportunity to visit it. There are 122 engravings designed by this important German artist and we can admire his great Melancolia I between them. We see a lot of geometrical instruments surrounding the main character of the picture but we must pay attention to the truncated rhombohedron with a faint human skull on it and the 4×4 magic square:
We can read the number 1514 on the lower row of the square which is the date of the engraving. As you can see, the four numbers of each row, each column and each diagonal sum up to 34. Durer was 43 when he painted this picture and maybe his passion for the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21, 34,…) was enough to reverse the two figures of the number of his age. So it was a very good opportunity to see this iconic picture in a real exhibition.
