Gemini decan 1: the decan lords of both systems

Gemini decan 1 covers 0°00′–9°59′ of Gemini, 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 Jupiter.

Jupiter as face lord gives the start of Gemini a wider frame than its usual quick curiosity. Questions grow into themes: not only what is this, but where does it lead. Reading, languages, short trips and long conversations all suit this stretch, and facts are collected into a view of how things fit together. The snag is gathering more threads than anyone can follow, and promising to read, write or visit more than the calendar can hold.

A planet here tends to emphasise learning that grows into a larger view of things. In practice, you start with a simple question, end up reading three books about it, and then wonder whether to learn the language of the place where it began.

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

Gemini with nothing added: the sign's own ruler and the sign's own habits. The mind is quick and curious, and attention moves across several subjects at once. Talking, texting, asking and comparing are the main tools. Starts are many and some stay unfinished. Of the three parts of Gemini this is the one that is most at home with switching topics mid-sentence and learning something just because it came up.

A planet here tends to emphasise curiosity and the exchange of information. In practice, you have several tabs open, start three conversations at once, and learn a new word or fact each day without trying.
