Locus Solus is the legendary novel by Raymond Roussel, first published in 1914. It is a word universe where the work of the eccentric French author reaches its peak. No longer published for decades, Locus Solus is now accessible again, enriched with commentaries, illustrations, a chronology, and an afterword. This rediscovery becomes a literary event through episodes from an original version that have never been published in French. We read about Bertha, the flower child, or Flio in the moonshadow of love. Stefan Zweifel, translator, publicist, and one of the great connoisseurs of French literature, has deciphered and translated them.
