First edition of this popular astrological folk-medicine guide, attributed to Johannes Müller von Königsberg, better known as Regiomontanus, the German astronomer and astrologer active in Vienna in the mid 15th century. Actual authorship is not known, but attribution to the well-regarded Regiomontanus certainly imparted commercial weight to the work, which appeared under several titles through the mid 16th century. The work relies in part on the field of iatromathematics, or the application of mathematical laws and precepts to the function and health of the human body, most notably for the practice of phlebotomy: a long section of the Natürlicher Kunst et Astronomei is devoted to a bloodletting calendar. Other sections are on sleep hygiene, mineral baths, purgation, preparation of medications, nutrition, and general health. Also contributing to the popularity of the work was its accessible and easily read charts, and bold illustrations (24 woodcuts in all), including an unusual homo sigorum, or Zodiac man, who here is opened up like a caviar sturgeon to reveal his innards, each organ connected by a line to a sign of the Zodiac. The woodcuts have been attributed to Hans Brosamer, but we cannot support this assertion. The printer, Christian Egenolff, was often in legal hot water for copying illustrations in the works of his contemporaries. A compelling and early work of German folk medicine. One copy in American libraries (Yale Medical).
