I must here, however, make particular mention of a man with whom I first became acquainted at this time, and whose instructive conversation so far blinded me to the miserable state in which I was, that I actually forgot it.  This was Langer, afterwards librarian at Wolfenbuettel.  Eminently learned and instructed, he was delighted at my voracious hunger after knowledge, which, with the irritability of sickness, now broke out into a perfect fever.  He tried to calm me by perspicuous summaries; and I have been very much indebted to his acquaintance, short as it was, since he understood how to guide me in various ways, and made me attentive whither I had to direct myself at the present moment.  I felt all the more obliged to this important man, as my intercourse exposed him to some danger; for when, after Behrisch, he got the situation of tutor to the young Count Lindenau, the father made it an express condition with the new Mentor that he should have no intercourse with me.  Curious to become acquainted with such a dangerous subject, he frequently found means of meeting me indirectly.  I soon gained his affection; and he, more prudent than Behrisch, called for me by night:  we went walking together, conversed on interesting things, and at last I accompanied him to the very door of his mistress; for even this externally severe, earnest, scientific man had not kept free from the toils of a very amiable lady.

German literature, and with it my own poetical undertakings, had already for some time become strange to me; and, as is usually the result in such an auto-didactic circular course, I turned back towards the beloved ancients who still constantly, like distant blue mountains, distinct in their outlines and masses, but indiscernible in their parts and internal relations, bounded the horizon of my intellectual wishes.  I made an exchange with Langer, in which I at last played the part of Glaucus and Diomedes:  I gave up to him whole baskets of German poets and critics, and received in return a number of Greek authors, the reading of whom was to give me recreation, even during the most tedious convalescence.

The confidence which new friends repose in each other usually develops itself by degrees.  Common occupation and tastes are the first things in which a mutual harmony shows itself; then the mutual communication generally extends over past and present passions, especially over love-affairs:  but it is a lower depth which opens itself, if the connection is to be perfected; the religious sentiments, the affairs of the heart which relate to the imperishable, are the things which both establish the foundation and adorn the summit of a friendship.
