The story behind Co-Significator
Traditional astrologers often used the Moon, planets in houses, and natural rulers as co-significators to refine judgment.
Co-Significator in spiritual tradition
Spiritually, Co-Significator asks whether added evidence is clarifying the reading or cluttering it.
Co-Significator in the Bible
Supporting testimony should increase humility, not become a way to force a desired result from the chart.
Why Co-Significator matters
Co-Significator matters because traditional charts often need more than one testimony. The Moon commonly supports the querent in horary, while planets in a relevant house may add context to the main ruler.
