The Four Angles
Four points anchor every chart. They are where two real lines in the sky, the horizon and the meridian, cut through the zodiac at your birthplace and birth time.
- ASCAscendant 14° SagittariusWhere the zodiac rises over the eastern horizon
- MCMidheaven 2° LibraWhere the zodiac crosses the meridian, high in the sky
- DSCDescendant 14° GeminiWhere the zodiac sets below the western horizon
- ICImum Coeli 2° AriesWhere the zodiac crosses the meridian, below the Earth
Arrows: the sky turns from east to west every day, so each sign in turn rises at the Ascendant, crosses the Midheaven and sets at the Descendant.
- The Ascendant is the sign rising in the east: how you meet the world.
- The Descendant, opposite it, is setting in the west: what you meet in others.
- The Midheaven (MC) is the highest point of the zodiac: your direction and public life.
- The Imum Coeli (IC) is the lowest: your roots and private base.
The angles move fast. A new sign rises roughly every two hours on average, faster or slower depending on the sign and the latitude. They are the reason a birth time matters, and the reason two people born on the same day can have very different charts.
