Each planet governed by three ranks of spirit
Agrippa's system, drawn largely from earlier Solomonic and Arabic sources, assigns each planet a three-tier hierarchy: a governing angel (the planet's divine intelligence in its purest, most benevolent aspect), a working intelligence (invoked in talismanic and sigil work), and a spirit (the planet's raw, unruly force — the name used with the most caution). Think of it the way a workshop has an owner, a foreman, and the machinery itself: the angel sets the intention, the intelligence carries it out, and the spirit is the power doing the physical work, indifferent to who's directing it.
Saturn
Saturn is the outermost of the classical planets and, to Renaissance eyes, the slowest and coldest — the planet of limitation, old age, structure, and the passage of time. Its magic is invoked for endurance, boundary, and long-term binding rather than speed or comfort. Agrippa-attested earlier Solomonic root
Jupiter
Jupiter is the great benefic — expansion, governance, wealth, and lawful authority. Talismans made under Jupiter were traditionally sought by those wanting favour with the powerful, or success in matters requiring good standing rather than force. Agrippa-attested
Mars
Mars governs conflict, courage, and cutting force — surgery as much as war, in the old correspondence. Its workings are the most cautioned-against in the Renaissance sources themselves, treated as necessary but volatile. Agrippa-attested
Sun
Though not a planet in the modern astronomical sense, the Sun holds the central seat in the classical seven — vitality, honour, kingship, and clarity. Solar talismans were the ones most often described as safe to make for oneself, unlike Saturn's or Mars's. Agrippa-attested
Venus
Venus rules love, beauty, harmony, and reconciliation — the gentlest of the seven workings in the traditional literature, aimed at drawing rather than compelling. Agrippa-attested
Mercury
Mercury governs communication, trade, learning, and cunning — the most changeable of the seven, said to take on the character of whichever planet it's paired with in a given working. Agrippa-attested
Moon
The Moon closes the classical sequence — the fastest-moving of the seven, governing travel, the tides, dreaming, and change. Lunar workings are timed more tightly than any other planet's, since the Moon's own phase and sign were held to matter as much as its hour. Agrippa-attested
