The Mysterious Life of Jeronimus Ruscelli and His Contribution to Nephrology (1504-1566).

Jeronimo Ruscelli was a mysterious humanist of great fame. He was born in Viterbo between 1504 and 1518 and died in Venice in 1566. Very little is known about Ruscelli's life, but based on his extensive literary output we can assume that he was endowed with remarkable intellectual abilities and a propensity for varied interests. At a young age, he developed a strong interest in classical studies and attended the court of Cardinal Marini Grimani in Utini. After completing his studies at the University of Padua, he participated in the founding of a humanist academy, the Accademia degli Sdegnati (the Scornful Academy). After his fruitful experience in Rome, he moved to the Neapolitan residence of Marquis Alfonso D'Avalos. Here, Ruscelli founded an "Academy of Secrets", composed of a group of humanists and nobles who had an extensive culture and had different experiences but similar interests. During these productive years, under the pseudonym Alexius Pedemontanus, he wrote one of his masterpieces, The Secreti, an important historical documentary manual of great value. In this book, the author proposes therapies for a wide variety of diseases, claiming in most cases that they have been experimentally and successfully tested in the presence of witnesses in at least 3 clinical cases. Ruscelli composed an extensive version of The Secreti, the Secreti Novi. In this book he reported more than a thousand recipes, the substances used were of a great variety and sometimes curious. According to Ruscelli, the recipes in this updated version of the book were "easy for anyone to make, of little effort, and useful for all kinds of people." The topics of this masterpiece range from general medical suggestions to more specific indications, with a wide variety of recipes and treatments of nephrological and urological interest.
