Product Highlight: Perpetual Moon Calendar
Athanasuis Kircher was a philosopher and mystic of the 17th century. In his beautiful illustration - originally titled 'The Selenic Shadowdial or the Process of the Lunation’ from "Ars Magna Lucis et Umbrae" (1646) - he joins together mathematics and mysticism. By using the growth properties of the arithmetical spiral, he makes it possible to read the hour of moonrise in each successive phase. The scheme gives the moon twenty-eight phases and the engraver, Pierre Miotte, has reversed the appearance of the waxing and waning moons for the northern hemisphere."
This perpetual calendar will assist the witch for years in planning rituals surrounding the phases of the moon, and detailing the time of its zenith to maximize the results.
