The Imum Coeli (IC) marks the 4th house cusp, symbolizing roots, home, family, and the foundation of personal identity.
Definition
The Imum Coeli (IC), Latin for 'lowest point,' is one of the four primary angles in an astrological chart. It represents the cusp of the 4th house and is located directly opposite the Midheaven (MC). The IC symbolizes one's private life, ancestral heritage, and the psychological foundation formed in early childhood. It is associated with the home environment, family relationships, and the emotional roots that shape one's inner world. Astrologically, the IC reflects the deepest, most personal aspects of an individual, often tied to their sense of security and belonging. Planets near or aspecting the IC can indicate significant influences from family dynamics or internalized experiences from the past. The IC also connects to themes of endings and introspection, as it represents the base of the chart where introspective growth occurs. While the MC looks outward toward public reputation, the IC focuses inward, anchoring the chart in personal history and emotional grounding.
In a chart
In a natal chart, the IC is the lowest point, found at the cusp of the 4th house. Look for the degree and sign at the base of the chart. Planets conjunct or aspecting the IC reveal influences tied to family, home, and personal foundations. Ignore outer planets unless tightly aspecting or conjunct.
