The aspect between the signs
Neighbouring signs share no element and no modality, and the traditional scheme counts them as “in aversion”, signs that cannot see each other. Each begins roughly where the other has just finished, which can be productive and can feel like talking past one another.
Elements and modalities
Fire is hot and dry, water cold and moist: they share no quality, and the classical scheme counts them as the most opposed pair of elements. Water can put out fire, and fire can evaporate water.
One sign starts and the other sustains: a cardinal sign opens, a fixed sign holds.
The rulers
The rulers are the Sun and the Moon, the two lights: one stands for identity and visibility, the other for need and response. Between them they name what each person wants to show and what each wants to be given.
Moon stands for: feeling, need, habit, memory. Sun stands for: identity, vitality, purpose, will.
The two signs together
Cancer tends to bring protectiveness: care, memory and a strong sense of home. It tends to need reassurance, and a safe place to say what it feels.
Leo tends to bring warmth: generosity, loyalty and a flair for making things an occasion. It tends to need appreciation, said aloud and meant.
Cancer protects and Leo shines, and each needs the other to notice. When the Moon’s moods meet the Sun’s pride, apology tends to be the hard part.
What tends to come easily
- Each brings something the other has not yet developed.
- Each has something the other lacks: warmth on one side, depth on the other.
- Starting and keeping are both covered.
- The wish to be seen and the wish to be cared for are both visible.
What tends to cost something
- There is little automatic understanding; common ground has to be built.
- The same intensity is felt by one as too much and by the other as too little.
- The starter can feel held back, and the sustainer can feel pushed.
- Being seen and being sheltered are different needs and can compete.
What two Sun signs cannot say
Two Sun signs are a small part of two charts. The Moon, Venus, Mars, the rising sign and the houses of each person shape how a relationship goes, and so do age, circumstance and choice.
The aspect here is counted between signs, not between degrees. Two people born at the start and at the end of the same sign stand differently from two born at the same degree, and this page cannot tell which applies.
To compare two actual people, the synastry tool takes both birth dates and shows the aspects between the planets.
