Atalanta Fugiens is considered by many to be the most beautiful and the most thought-provoking emblem book of all time, with an author in Michael Maier (1568-1622) who was a celebrated alchemist and physician at the court of the Emperor Rudolf II in Prague. In the final eight years of an eventful and much-travelled life, Maier created a series of illustrated alchemist works, among which Atalanta Fugiens is undoubtedly the most important. Part of the fascination which this work has aroused stems from its tripartite nature: from a visual perspective with all its engraved emblems, as a musical work comprising fifty compositions,identified as 'fugues', which run through the publication and accompanying the images, and as a purely textual activity in the form of a volume of epigrams and alchemic commentaries. Additionally, Atalanta Fugiens provides part of the backdrop to an understanding of the spiritual Rosicrucian movement which flourished during the first decades of the 17th century, especially in the German principalities. The musical pieces, of an extremely antiquated nature even for that time, consist of canons in two parts above a cantus firmus; Michael Noone and his Ensemble Plus Ultra perform them in their entirety and in the order in which they appear in the book. What emerges through the centuries across this book is a hypnotic disc, one that is unclassifiable yet extraordinarily evocative.
