Giuliano Kremmerz (1861-1930) was the most important Italian esoterist and his works have been translated into French, Portuguese and Spanish. Kremmerz was initiated by Pasquale De Servis (1818-1893) who introduced him into the milieu of Neapolitan and Egyptian magic, whose leading exponent was the Attorney and Freemason Giustiniano Lebano (1832-1910). Kremmerz soon departed from the latter, to found the Fratellanza terapeutico-magica di Miriam. It was a Brotherhood that dealt with occult medicine. Its members tried to cure the sick through individual and collective magic rituals. The Brotherhood had an occult organism that governed it. It was the Egyptian Osirid Order, in which high ceremonial magic and sexual magic were practiced as instruments of asceticism to the so-called One Infinite. Angels and Demons of Love is a first attempt by the Kremmerz to bring the attention of readers of the end of the XIX century, on the subject of the evolution of man, passing through the so-called internal alchemy.
