The 1st decan of Scorpio: the meaning

As at the start of Aries, both systems name Mars.

In the Chaldean order, it follows Jupiter, ruler of the end of Libra; in the triplicities, the first decan belongs to Scorpio itself and to its traditional master. Modern astrologers, who also give Pluto to the sign, would see there a double intensity, that of action and that of transformation.

One would describe a person who commits totally: to a friendship, a line of research, an endurance sport, a cause. They go all the way, stopping for neither obstacles nor fatigue. They observe before acting, then act with a determination that impresses. Difficult subjects, money, jealousy, unspoken family matters, do not frighten them; they would rather look an unpleasant truth in the face than live in illusion.

The downside would be all or nothing. A disappointment might lead to a clean break, with no explanation and no way back. Once distrust sets in, it would be hard to dispel. This third would do well to leave a door ajar, even after a serious quarrel, to admit half-measures when they protect a precious bond, and to voice its anger before it turns into permanent silence. A stormy explanation is often worth more than a door closed forever.

Frequently asked questions about the 1st decan of Scorpio

Which planet rules the 1st decan of Scorpio?

Mars, in both systems: Chaldean face after Jupiter, and master of Scorpio in the triplicities, which give the first slice of the sign to its own master. Pluto is added for those who adopt 20th-century rulerships. It is one of the rare decans where the question of the ruler is not debated.

Is the 1st decan of Scorpio the most intense?

Tradition describes it as the most wholehearted of the sign, Mars ruling alone. The supposed intensity would translate into strong commitments and firm refusals. This is only a symbolic angle: the Moon, Venus, and rising sign describe far better how a person lives their emotions and attachments.

What are the dates of the 1st decan of Scorpio?

This third starts when the Sun enters Scorpio, in the last days of October, then extends for about ten days, until the first days of November. Like all decans, its limits change slightly each year. The engine calculates them to the minute and presents them for three autumns, in Paris time, standard time included.
