But Rahel was not always in a position to comfort others. In her young days she stood sorely in need of comfort herself. By nature she was of such an irritably nervous temperament that as a child she was with difficulty kept in life: "Let the air be too dense or too rare, too warm or too cold, and I am ill at once. And the slightest excitement has a still worse effect. I cannot imagine any one more sensitive." In nearly all her letters, immediately after the date, we find a detailed description of the weather and temperature: "Friday, 14th March, 1828.--A grey day, with south-west wind, damp and yet spring-like, though not inviting for a walk. Pigeons are flying. Every now and then a blue window appears in the sky; at this moment sunlight is coming through one of them." "23rd March, 1829.--The sun has broken through the clouds and is shining brightly; a cold, sharp, unmistakable north-east wind; impossible to go to the Thiergarten, where there is still ice and it is as cold as in a cellar." "17th April,--Noon; spring weather after rain; the trees turning green. To me the best time of the whole year--no flies or mosquitoes, no heat. Spring is approaching, wafting to us a thousand memories, and a thousand hopes which can never be fulfilled, but which are a necessity to us." Such natures deserve and arouse as much compassion as admiration. Her friend, W. von Burgsdorf, writes to her: "When I saw you for the first time, it struck me at once that you must have been educated by long suffering." It was true; she had had an infirm body, a melancholy youth, a severe father, and had early suffered humiliation. Her Jewish birth was the cause of great unhappiness to her--an unhappiness almost unworthy of her; she calls it a sword thrust into her heart by a supernatural being at the moment of her birth. Not one fibre in her nature attached her to the religious community to which by birth she belonged. The memory of its fanaticism and of the fanatical enmity displayed towards it was still fresh. As lately as 1756 the Jewish community in Berlin had expelled a child from the town for having carried a book for a Christian. And on the other side, even Moses Mendelssohn could not go out with his children without having stones thrown at them. With all the power of his intellect and will, Rahel's father had striven to overcome the sickly child's independence of character, and only her unusual elasticity and strength of mind enabled her to preserve her originality. When young she felt as if she had suffered so much there could not possibly be anything left in her to be bent or broken. It was inevitable that a woman with this passionate nature should love passionately and should suffer agony through her love. And she did not escape her fate. Twice, when she loved most ardently, she experienced as it were the feeling of being struck down with an assassin's knife and of living for years with the knife in the wound.
