Shevilei Emunah [astronomical, medical, ethical and kabbalistic encyclopedia].

Meir Aldabi, who lived in the 14th century, was a grandson of the Ro”sh (Asher ben Yechiel). This popular work combines the author’s predilection for Kabbalah together with a knowledge of philosophy, medicine and science. It contains ten sections entitled “Nethivim” (roads), subdivided into chapters, “Shevilim” (paths). The work was reprinted many times and served as a source of scientific information for generations. De Fonseca’s Hebrew press at Amsterdam was operative for only one year, during which time he printed just two Hebrew books.
