Composite readings

Composite Mars to the Midheaven

A composite chart is built from the midpoints between two people's charts, so it is one chart for the pair rather than a chart for either person. These readings say what a placement in it stands for in a pair's shared chart.

Together

Composite Mars conjunct with the Midheaven
The pair's standing is tied to energy and initiative, as its drive and its public direction act as a single force. Effort and ambition tend to start from the same impulse.
Composite Mars in an easy aspect with the Midheaven
The pair's effort runs in step with its aims, so energy goes into what it is building in public. Action tends to follow direction, and direction to give action a clear target.
Composite Mars in a hard aspect with the Midheaven
The pair's drive and its chosen direction pull in different directions. Effort goes one way while the aim points another.

None of this is a verdict. A single placement never describes a whole relationship, and astrology is a tradition of interpretation rather than a body of established fact.
