From late 1899, Hesse worked in a distinguished antique book shop in Basel. Through family contacts, he stayed with the intellectual families of Basel. In this environment with rich stimuli for his pursuits, he further developed spiritually and artistically. At the same time, Basel offered the solitary Hesse many opportunities for withdrawal into a private life of artistic self-exploration, journeys and wanderings. In 1900, Hesse was exempted from compulsory military service due to an eye condition. This, along with nerve disorders and persistent headaches, affected him his entire life.
