What Is the Imum Coeli (IC) & The IC in the 12 Zodiac Signs

What Is the Imum Coeli (IC)

In astrology, the Imum Coeli (IC), also known as the Nadir or Fourth House Cusp, marks the lowest point of the natal chart. It represents the foundation of one’s being: home, family, roots, and the private inner self. While the Midheaven (MC) points upward toward career and public life, the IC points inward and downward, symbolizing the personal world that lies beneath the surface. It governs:

• Childhood environment and early family influences.

• Ancestral heritage and cultural roots.

• Inner emotional foundation and sense of security.

• The home environment one creates later in life.

The IC reveals where a person feels most at home and safe, shaping their inner stability and the emotional soil from which they grow.
