Sagittarius decan 1: the decan lords of both systems

Sagittarius decan 1 covers 0°00′–9°59′ of Sagittarius, the first ten degrees, where the sign begins. In the Chaldean system each ten-degree slice has a lord called the face, and here it is Mercury.

Mercury as face lord gives the start of Sagittarius a mind that jumps between big ideas and small facts. Candour is high and the details occasionally get lost on the way. Teaching, writing, debating and explaining a view to a crowd suit this stretch. Plans are announced with enthusiasm and sometimes without a method behind them, so a promise made in a good mood may need a second look before it is turned into a schedule.

A planet here tends to emphasise talking about ideas. In practice, you tell a story with a strong opinion at the end, check the facts afterwards, and sometimes revise the opinion.

Sagittarius decan 1 covers 0°00′–9°59′ of Sagittarius, the first ten degrees, where the sign begins. In the triplicity system its sub-sign is Sagittarius itself, so the lord is the sign's own ruler, Jupiter.

Sagittarius in its plainest form. Candour, optimism and the search for meaning are all in the foreground. Plans are broad, trips are imagined before they are booked, and beliefs are held openly. Enthusiasm sometimes outruns follow-through. Of the three parts of Sagittarius this is the one that is most at home with a question that has no final answer, and the least bothered by being wrong in public.

A planet here tends to emphasise belief and exploration. In practice, you sign up for the trip, the course or the debate without knowing all the details, and treat a surprise as part of the point.
