The Symbolist Ėllis’ (Lev Kobylinskij) writings during his Moscow period emphasize the split, the division and dichotomy between material reality and celestial vision. His works written in exile in Locarno-Monti in Switzerland are devoted to resolving these antitheses by building bridges on all levels: between Catholicism and Orthodoxy, between culture and religion, between worldly and otherworldly, ultimately between East and West. From being a poet and critic he became a translator and culturologist: “Dr. Leo Kobilinski-Ellis.” The Dutch medium Johanna van der Meulen — whom he had met in 1911 in Rudolf Steiner’s Theosophical, soon Anthroposophical colony — played a crucial role in this fundamental metamorphosis. With her he lived in a thirty-five-year-long creative symbiosis that proved extremely beneficial to the two of them. Van der Meulen developed a mystical doctrine of her own, “Cosmosophy”, based on a Gnostic world view, strongly influenced by Russian religious philosophy. As she had finished her work in four parts Dr. Kobilinski-Ellis published his summary and interpretation of her teachings, in which he defines the core of Cosmosophy as a synthesis of the “Johannian” element in the meditative wisdom of the Eastern Church and the “Petrine” component in the energetic faith of Catholicism.
