Third Decan of Virgo (20°–30°)

Mercury's sign, Mercury's face, Venus behind

The third decan of Virgo covers 20°–30° of the sign, the last stretch before the Sun reaches the autumn equinox and Libra. In the Chaldean order this face belongs to Mercury, which also rules Virgo, so a planet here sits in a sign and a face with the same lord. In the triplicity order the face belongs to Taurus, the third earth sign by Virgo's count, and so to Venus. The decan also contains Venus's fall degree, 27° Virgo.

Astrologers read this face as Virgo completing its work. The first decan learns the craft and the second builds comfort; the third organises, records and passes things on. Mercury doubled at sign and face level gives analysis, memory and system. Venus through Taurus adds a sense of lasting value and a feel for what is worth keeping. The result is a talent for estates in the broad sense: archives, households, collections, institutions. The risk is anxiety about loss, and a wish to control everything so nothing slips.

The old man with a staff and the jar of dark oil

Agrippa's Three Books of Occult Philosophy (1533) describes this face as a pale woman who cannot hear, or an old man leaning on a staff, and he reads it as weakness, the loss of strength in the limbs, the felling of trees and lands emptied of people. The Picatrix, the Arabic manual of astral magic behind Agrippa's lists, gives a tall, pale man wrapped in white linen and beside him a woman holding black oil, and reads the face as age, fatigue, idleness, injury and the clearing of trees.

These are images of autumn, when the harvest is over and the fields stand bare. Read today, they speak less about any person's body than about the end of a cycle: what ages, what has to be cleared, what will be left for others. The old man with the staff becomes, in the tarot, the patriarch of the Ten of Pentacles. The Golden Dawn's title, Lord of Wealth, shows the other side of the same moment: what a long life of work leaves behind.

Egyptian star names in Greek letters

Before it closed Virgo, this face was one of the thirty-six star groups whose dawn risings told the Egyptian nights and marked ten-day weeks. The Egyptian lists differ in order and content, so no particular star can be assigned to 20°–30° of the tropical zodiac with confidence.

The Mercurial part of the story is the names. When Greek-speaking astrologers in Egypt took the decans into the zodiac, three to a sign, they kept the decan names and wrote them in Greek letters. Hephaistion of Thebes gives a list of thirty-six, and a few can still be traced to their Egyptian originals, Sothis from Sopdet among them, though repeated copying wore most of them down beyond recognition. Keeping an inventory alive across languages and centuries is a fitting history for Virgo's last face. The decans' life as gods is described on the Egyptian decan gods page.

The Ten of Pentacles: Mercury in Virgo

In the Golden Dawn system this decan is the Ten of Pentacles, Mercury in Virgo, which Book T calls the Lord of Wealth. Pamela Colman Smith's Rider-Waite image shows an old man in a patterned cloak sitting by an archway with two white dogs, while a couple and a child stand beyond it. Ten pentacles are laid over the scene in the pattern of the Kabbalistic Tree of Life, and an estate rises behind them.

The card shows Mercury in its own sign doing what it does best in earth: ordering things so that they can be passed on. The ten completes the suit, wealth in the full sense of family, property, records and custom. The two trumps behind the pip are The Magician for Mercury and The Hermit for Virgo, skill and solitary wisdom. The old man has both. Readers in the tradition take the card as security that spans generations, and as a question about what one inherits and what one leaves.

A Sun or planets in the third decan of Virgo

With the Sun here, born from roughly the 12th or 13th to the 22nd of September depending on the year, you have Virgo's ruler in charge of the face as well. You may think in systems and long timelines, and feel responsible for keeping things running, whether a household, a team or a family's history. Your analysis is practical and your memory for detail is strong. Venus through Taurus gives you a quiet appreciation of good, lasting things. The growth point is letting go: accepting that not everything can be kept in order, and that some endings make room.

Several planets in these degrees give a chart a strong sense of duty, structure and inheritance. Mercury here is at home and in its own face, so it is unusually strong. Venus near 27° is at her fall degree and leans heavily on the condition of Mercury, the ruler of the sign she is in.

Working with the third decan of Virgo

Make a record of something that matters to your family or community: recipes, stories, photographs, a craft method. This decan finds meaning in preserving. Review your systems once a season and clear out what no longer serves, as the old images of felled trees suggest; maintenance includes removal. Write down what you would want to hand on, whether money, skills or values, and talk about it with the people concerned. If you read tarot, set the Ten of Pentacles between The Magician and The Hermit and ask what you are building that will outlast you. Rest is part of upkeep, so plan it as carefully as the work.
