The most famous book of German Humanism, Libri Quatuor Amorum Secundum Quatuor Latera Germaniae of Konrad Celtis (1459–1508), containing 47 love elegies and a prose description of the imperial city of Nuremberg, was printed at Nuremberg in 1502. It is dedicated by Celtis to Maximilian I, King (later Emperor) of the Romans and Archduke of Austria. Its beginning is decorated by woodcuts of the leading artist Albrecht Dürer. A poetical Panegyricus on Maximilian I with 167 Latin hexameters, composed by Celtis’ friend Vincentius Longinus, is placed at its end. It is not only a laudatory poem for Maximilian, who is finally compared with Hercules and Atlas, but it also deals generally with Apollo, the Muses, Bacchus and the Turks in those times, thus giving a strong political and spiritual message at the end of the book. The local goal of the Muses, Apollo and Bacchus, who had to leave Greece because of the Turks, is the mountain Cecius at the Danube near Vienna. Contrary to the elegies of Celtis in this book, which are extensively discussed and interpreted in research literature, the poem of Longinus did not find much attention. Therefore, this paper is giving a new edition, the first translation and the first commentary to that important text.
