The article considers the phenomenon of reception of Paracelsiana in Russia in the 18th - first half of the 19th centuries based on archival sources from the libraries of Moscow and St. Petersburg. For the first time the paper introduces a number of documents with the earliest Russian Paracelsus translations, which allow to highlight a range of texts particularly interesting for the Russian academic community. The original works and notes of Dimitrie Cantemir, Vasily Tatishchev, Alexander Klushin, Akim Nakhimov, Johann Georg von Schwarz, Peter Titov, Semyon Gamaleya and many other authors are viewed for the first time through the prism of the history of Paracelsianism. The article raises the question of the significance of the books by Paracelsus for the intellectual history of Russia. They are considered in the light of their reception in the works of intellectuals from the so-called Friendly Scientific Society at the Imperial Moscow University, as well as in the works of German naturalists in the Russian service related to the history of the Imperial St. Petersburg Academy of Sciences.
