The seven planets as the Renaissance magician understood them

This is a reference on the seven classical planets as objects of ritual practice in the Hermetic and Renaissance magical tradition — the metals they govern, the intelligences and spirits assigned to them, the hours named for them, and the talismans built to catch their influence. It draws primarily on Marsilio Ficino's De Vita Coelitus Comparanda, Cornelius Agrippa's Three Books of Occult Philosophy, and the older Arabic Picatrix that fed both.

If you're looking for the astrological end of this — how the planets are read and invoked through a horoscope rather than through ritual, metal, and hour — that's the focus of its sister reference, astrotheurgy.com. The two overlap at the edges; this site stays on the workshop side of the practice.
