In December, 1896, Strindberg returned to Sweden. Swedenborg's _Arcana Cœlestia_, which he now read, dissipated his fears of persecution by showing him that all the horrors through which he had passed, were recognised by Swedenborg as incidental to the purgation of soul which is the highest object of life. Strindberg found that, before receiving his momentous revelations, Swedenborg had passed through nightly tortures resembling his own. By informing him of the real nature of the horrors Swedenborg liberated him from the electricians, the black magicians, the destroyers, the jealous gold-makers, and the fear of madness. "He has shown me the only path to salvation: to seek out the demons in their dens within myself, and to kill them ... through repentance." _Inferno_ was composed in Lund, the little University town in the south of Sweden, between May 3rd and June 25th, 1897. _Legends_, which is but a rifacimento of the struggle to slay the "demons in their dens," was begun in Lund, and finished in Paris in October, 1897. In March, 1898, Strindberg went back to Lund, free from haunting obsessions of evil, master of his madness, enriched by religious experiences which produced an exuberant rise of new ideas. He had crossed the Rubicon. Henceforth he shared in that direct vision which makes paralysing doubt impossible, and which is the prerogative of God's fools all over the world. To the end of life his mind retained intellectual disquiet; there remained in him a strain of the wild man, an over-balance of curiosity which set up eternal enmity between him and convention. The Swedish critic, Oscar Levertin, succinctly summed up Strindberg in the Italian proverb: _All soul, all gall, all fire_. But after 1898 there is a calm light which the unruly flames cannot hide. His spiritual wrestlings continue through the zenith of his literary production, but they leave him stronger.
