2576      <tm:resourceData datatype="http://www.w3.org/2001/XMLSchema#string">Who rides there so late through the night dark and drear?
2577The father it is, with his infant so dear;
2578He holdeth the boy tightly clasp'd in his arm,
2579He holdeth him safely, he keepeth him warm.
2580
2581"My son, wherefore seek'st thou thy face thus to hide?"
2582"Look, father, the Erl-King is close by our side!
2583Dost see not the Erl-King, with crown and with train?"
2584"My son, 'tis the mist rising over the plain."
2585
2586"Oh, come, thou dear infant! oh come thou with me!
2587For many a game I will play there with thee;
2588On my strand, lovely flowers their blossoms unfold,
2589My mother shall grace thee with garments of gold."
2590
2591"My father, my father, and dost thou not hear
2592The words that the Erl-King now breathes in mine ear?"
2593"Be calm, dearest child, 'tis thy fancy deceives;
2594'Tis the sad wind that sighs through the withering leaves."
2595
2596"Wilt go, then, dear infant, wilt go with me there?
2597My daughters shall tend thee with sisterly care
2598My daughters by night their glad festival keep,
2599They'll dance thee, and rock thee, and sing thee to sleep."
2600
2601"My father, my father, and dost thou not see,
2602How the Erl-King his daughters has brought here for me?"
2603"My darling, my darling, I see it aright,
2604'Tis the aged grey willows deceiving thy sight."
2605
2606"I love thee, I'm charm'd by thy beauty, dear boy!
2607And if thou'rt unwilling, then force I'll employ."
2608"My father, my father, he seizes me fast,
2609For sorely the Erl-King has hurt me at last."
2610
2611The father now gallops, with terror half wild,
2612He grasps in his arms the poor shuddering child;
2613He reaches his courtyard with toil and with dread,--
2614The child in his arms finds he motionless, dead.</tm:resourceData>

2654      <tm:resourceData datatype="http://www.w3.org/2001/XMLSchema#string">Auch ich war in Arkadien geboren,
2655Auch mir hat die Natur
2656An meiner Wiege Freude zugeschworen,
2657Auch ich war in Arkadien geboren,
2658Doch TrÀnen gab der kurze Lenz mir nur.
2659
2660Des Lebens Mai blÃŒht einmal und nicht wieder,
2661Mir hat er abgeblÃŒht.
2662Der stille Gott - o weinet, meine BrÃŒder -
2663Der stille Gott taucht meine Fackel nieder,
2664Und die Erscheinung flieht.
2665
2666Da steh ich schon auf deiner SchauerbrÃŒcke,
2667EhrwÃŒrdge Geistermutter - Ewigkeit.
2668Empfange meinen Vollmachtbrief zum GlÃŒcke,
2669Ich bring ihn unerbrochen dir zurÃŒcke,
2670Mein Lauf ist aus. Ich weiß von keiner Seligkeit.
2671
2672Vor deinem Thron erheb ich meine Klage,
2673VerhÃŒllte Richterin.
2674Auf jenem Stern ging eine frohe Sage,
2675Du thronest hier mit des Gerichtes Waage
2676Und nennest dich Vergelterin.
2677
2678Hier - spricht man - warten Schrecken auf den Bösen,
2679Und Freuden auf den Redlichen.
2680Des Herzens KrÃŒmmen werdest du entblößen,
2681Der Vorsicht RÀtsel werdest du mir lösen
2682Und Rechnung halten mit dem Leidenden.
2683
2684Hier öffne sich die Heimat dem Verbannten,
2685Hier endige des Dulders Dornenbahn.
2686Ein Götterkind, das sie mir Wahrheit nannten,
2687Die meisten flohen, wenige nur kannten,
2688Hielt meines Lebens raschen ZÃŒgel an.
2689
2690»Ich zahle dir in einem andern Leben,
2691Gib deine Jugend mir!
2692Nichts kann ich dir als diese Weisung geben.«
2693Ich nahm die Weisung auf das andre Leben,
2694Und meiner Jugend Freuden gab ich ihr.
2695
2696»Gib mir das Weib, so teuer deinem Herzen,
2697Gib deine Laura mir.
2698Jenseits der GrÀber wuchern deine Schmerzen.« -
2699Ich riß sie blutend aus dem wunden Herzen
2700Und weinte laut und gab sie ihr.
2701
2702»Du siehst die Zeit nach jenen Ufern fliegen,
2703Die blÃŒhende Natur
2704Bleibt hinter ihr - ein welker Leichnam - liegen.
2705Wenn Erd und Himmel trÃŒmmernd auseinanderfliegen,
2706Daran erkenne den erfÌllten Schwur.«
2707
2708»Die Schuldverschreibung lautet an die Toten«,
2709HohnlÀchelte die Welt,
2710»Die LÌgnerin, gedungen von Despoten,
2711Hat fÃŒr die Wahrheit Schatten dir geboten,
2712Du bist nicht mehr, wenn dieser Schein verfÀllt.«
2713
2714Frech witzelte das Schlangenheer der Spötter:
2715»Vor einem Wahn, den nur VerjÀhrung weiht,
2716Erzitterst du? Was sollen deine Götter,
2717Des kranken Weltplans schlau erdachte Retter,
2718Die Menschenwitz des Menschen Notdurft leiht?
2719
2720Ein Gaukelspiel, ohnmÀchtigen GewÌrmen
2721Vom MÀchtigen gegönnt,
2722Schreckfeuer, angesteckt auf hohen TÃŒrmen,
2723Die Phantasie des TrÀumers zu bestÌrmen,
2724Wo des Gesetzes Fackel dunkel brennt.
2725
2726Was heißt die Zukunft, die uns GrÀber decken?
2727Die Ewigkeit, mit der du eitel prangst?
2728EhrwÃŒrdig nur, weil schlaue HÃŒllen sie verstecken,
2729Der Riesenschatten unsrer eignen Schrecken
2730Im hohlen Spiegel der Gewissensangst;
2731
2732Ein LÃŒgenbild lebendiger Gestalten,
2733Die Mumie der Zeit,
2734Vom Balsamgeist der Hoffnung in den kalten
2735Behausungen des Grabes hingehalten,
2736Das nennt dein Fieberwahn - Unsterblichkeit?
2737
2738FÃŒr Hoffnungen - Verwesung straft sie LÃŒgen -
2739Gabst du gewisse GÃŒter hin?
2740Sechstausend Jahre hat der Tod geschwiegen,
2741Kam je ein Leichnam aus der Gruft gestiegen,
2742Der Meldung tat von der Vergelterin?" -
2743
2744Ich sah die Zeit nach deinen Ufern fliegen,
2745Die blÃŒhende Natur
2746Blieb hinter ihr, ein welker Leichnam, liegen,
2747Kein Toter kam aus seiner Gruft gestiegen,
2748Und fest vertraut ich auf den Götterschwur.
2749
2750All meine Freuden hab ich dir geschlachtet,
2751Jetzt werf ich mich vor deinen Richterthron.
2752Der Menge Spott hab ich beherzt verachtet,
2753Nur deine GÃŒter hab ich groß geachtet,
2754Vergelterin, ich fodre meinen Lohn.
2755
2756"Mit gleicher Liebe lieb ich meine Kinder!"
2757Rief unsichtbar ein Genius.
2758"Zwei Blumen", rief er, "- hört es, Menschenkinder -
2759Zwei Blumen blÃŒhen fÃŒr den weisen Finder,
2760Sie heißen Hoffnung und Genuß.
2761
2762Wer dieser Blumen eine brach, begehre
2763Die andre Schwester nicht.
2764Genieße, wer nicht glauben kann. Die Lehre
2765Ist ewig wie die Welt. Wer glauben kann, entbehre.
2766Die Weltgeschichte ist das Weltgericht.
2767
2768Du hast gehofft, dein Lohn ist abgetragen,
2769Dein Glaube war dein zugewognes GlÃŒck.
2770Du konntest deine Weisen fragen,
2771Was man von der Minute ausgeschlagen,
2772Gibt keine Ewigkeit zurÃŒck."</tm:resourceData>
