The Magical Calendar is one of the most amazing pieces of art and information available in Western Hermeticism.
Published in 1620, the Magical Calendar contains tables of correspondences arranged by number from one to twelve. They are based in part on extensive tables in Agrippa, book 2, chapters 4-14 but go well beyond anything in Agrippa, especially sigils. The engraving was executed by the brilliant Johannes Theodorus de Bry who illustrated other important occult works such as those of Robert Fludd. The author was Johann Baptista Großchedel. Carlos Gilly has identified the original manuscript on which the printed Magical Calendar was based as British Library manuscript Harley 3420.
Adam McLean published a wonderful study of it in The Magical Calendar: A Synthesis of Magical Symbolism from the Seventeenth-Century Renaissance of Medieval Occultism (available via amazon.com)
A bat first grew wings and of the proper kind, by its desire being organic enough to reach the sub-consciousness. If its desire to fly had been conscious, it would have had to wait till it could have done so by the same means as ourselves, i.e. by machinery.
