The next two years saw the production of several exquisite works, in particular the epic of "Thors Reise til Jotunheim", the poem in hexameters called "Langelandsreisen", and the bewitching fantasy "Aladdin" (1805). At the age of twenty-six, Oehlenschläger was universally recognised, even by the opponents of the romantic revival, as the leading poet of Denmark. He now collected his "Poetical Writings" in two volumes. He found no difficulty in obtaining a grant for foreign travel from the government, and he left Denmark for the first time, joining Steffens at the University of Halle in August 1805. Here he wrote the first of his great historical tragedies, "Hakon Jarl", which he sent off to Copenhagen, and then proceeded for the winter months to Berlin, where he associated with Wilhelm von Humboldt, Johann Gottlieb Fichte and met Goethe for the first time.
