To all, To the list with links to sundial pages is added a link to : Horologium Augusti (Geodätisches Institut der Universität Karlsruhe TH)
At these pages a number of photographs are placed in a repeating background with pictures from the book by Edmund Buchner, titled "Die Sonnenuhr des Augustus", 1982. This beautifull book was published after important excavations in Rome. At the page "Ergebnis" also the bird's view is given. In the middle of that picture 2 curved lines are drawn. As Buchner wrote these lines perhaps could have been present in August's dial and the lines show the time a certain day is longer then the shortest day in winter. (daylight triangle) It is proofed that Buchner had made an error in calculatimg and drawing this daylight triangle. The lines of this triangle have to be straight lines. I published an article in the bulletin of "De Zonnewijzerkring" (september 1984) about this matter and in the next bulletin (january 1985) René Rohr gave another and more elegant proof that these lines have to be straight lines. I point to this because I would regret false pictures of this amazing sundial being published all around the world. In the little book "A sundial for yuur garden" by Harold E. Brandmaier, 1995, page 2-10, a drawing with straight lines can be seen. At that time I was very pleased to see a correct drawing of the daylight triangle been published.
