Example: Martin Luther, 1483.
Scorpio 4th House stellium.
Note that Mars is sole dispositor.
To see chart, go to Google, say "horoscope of Martin Luther".
What's it good for?
Well, it might be bad...depends.
What did it produce in Luther's life?
There's your answer.
I have a friend with a Scorpio 4th stellium. I think she mostly lives her life in the comfort, security and peace of her home. Until Luther was around 35 he lived in the bosom of the Church; similar?
But you cannot make blanket statements. Too many variables.
