About the 3rd House

In the ancient sense, the Third House was the House of the Moon.

It contains everything familiar to you. Of course, it associates with brothers and sisters but also the people you see around the neighborhood or the coworkers you see every day. It’s also your habits and routines and the places you visit on a regular basis – short-distance trips to school or work or the grocery store. Basically, it’s your comfort zone.

The Moon was also associated with writing and bringing the messages of the other planets down to Earth. So, the 3rd house in birth charts contained those things too.

Modern Astrologers commonly refer to the “Natural House System” as opposed to the ancient Hellenistic Astrological approach of using what is called the “Planetary Joys”
