The Calendarium Naturale Magicum Perpetuum Is A Late Renaissance (c.1619 Or 1620) Grimoire And Esoteric

The Calendarium Naturale Magicum Perpetuum is a late renaissance (c.1619 or 1620) grimoire and esoteric print of calendar engravings. Its full title is Magnum Grimorium sive Calendarium Naturale Magicum Perpetuum Profundissimam Rerum Secretissimarum Contemplationem Totiusque Philosophiae Cognitionem Complectens. It measures more than four feet long and about two feet wide, and includes an early example of a Pentagrammaton.

The “author” in the 1619/1620 Frankfurt print is given as Johann Baptist Grossschedel von Aicha, and attributes some of the engravings to Tycho Brahe. The original engraver is given as Theodor de Bry, as first published in 1582. This work predated, and influenced, the Rosicrucian furor.
