Passage: In 1881, when Hesse was four, the family moved to Basel, Switzerland, staying for six years and then returning to Calw. After successful attendance at the Latin School in Göppingen, Hesse entered the Evangelical Theological Seminary of Maulbronn Abbey in 1891. The pupils lived and studied at the abbey, one of Germany's most beautiful and well-preserved, attending 41 hours of classes a week. Although Hesse did well during the first months, writing in a letter that he particularly enjoyed writing essays and translating classic Greek poetry into German, his time in Maulbronn was the beginning of a serious personal crisis. In March 1892, Hesse showed his rebellious character, and, in one instance, he fled from the Seminary and was found in a field a day later. Hesse began a journey through various institutions and schools and experienced intense conflicts with his parents. In May, after an attempt at suicide, he spent time at an institution in Bad Boll under the care of theologian and minister Christoph Friedrich Blumhardt. Later, he was placed in a mental institution in Stetten im Remstal, and then a boys' institution in Basel. At the end of 1892, he attended the Gymnasium in Cannstatt, now part of Stuttgart. In 1893, he passed the One Year Examination, which concluded his schooling. The same year, he began spending time with older companions and took up drinking and smoking.After this, Hesse began a bookshop apprenticeship in Esslingen am Neckar, but quit after three days. Then, in the early summer of 1894, he began a 14-month mechanic apprenticeship at a clock tower factory in Calw. The monotony of soldering and filing work made him turn himself toward more spiritual activities. In October 1895, he was ready to begin wholeheartedly a new apprenticeship with a bookseller in Tübingen. This experience from his youth, especially his time spent at the Seminary in Maulbronn, he returns to later in his novel Beneath the Wheel.
