All who are familiar with Heine's works or letters are aware of the warm friendship and brotherhood in arms that united him in his youth to Karl Immermann. He proposed to Immermann to insert some of his epigrams in the _Reisebilder_, and as a matter of fact there are several pages of them in the book between the divisions _Norderney_ and _Das Buch Le Grand_. They satirise various literary personages and events of the day. The attacks on those writers who imitated Oriental forms of poetry incensed Platen, and induced him to write his dramatic satire, _Der romantische Oedipus_, which in its turn called forth Heine's well-known satire. It was very curious that Platen, in his irritation, should with one blow stamp as Romanticists the two men who, each in his own way, did so much (more than Platen himself) to unswathe from the wrappings of Romanticism a new spirit, a new art--the spirit, the art of modern poetry. Karl Immermann (born in 1796) was three years older than Heine. He was the son of a correct, austere Government official in Magdeburg, and was himself a man of strong character and solid culture, early imbued with that old Prussian spirit of which there was not a trace in Heine. They were contrasts in almost everything. Immermann fought in the battle of Waterloo as a volunteer, entered Paris with the army, afterwards retired with the rank of an officer, and studied law at the University of Halle. His strong feeling of justice led him into disputes with the powerful students' union, Teutonia, which had usurped a kind of moral authority over all the students, and enforced its principles, especially that of purity of life, in a domineering, brutal fashion. For several years he continued to oppose the practices of the Union, and more than once during this time was obliged to invoke the power of the law to protect him from the insults and persecution to which he was subjected by his antagonists. The consequence of this was that he was hated by the great majority as an informer--the more so as the political reactionaries took advantage of this opposition to the traditional malpractices of the students' unions, to attack, and, where it was possible, suppress the unions, a proceeding for which Immermann was in no way responsible. From this time onwards he stood alone. Much in his character, much of its dryness and peculiarity, had its origin in this isolation, which also favoured the development of pride and self-esteem. [Illustration: IMMERMANN] In 1819, Immermann was given a Government appointment (that of _Divisionsauditor_), in the town of Münster, in Westphalia, an old, strictly Catholic, provincial town, where at first he felt himself out of sympathy with every one and everything. But here, ere long, he made acquaintance with the woman who was to be the most powerful influence in his life.
