"Most astrologers accept as fact that Saturn, the Greater Malefic, located in the natal 10th house of fame, status, and career indicates a problematic career, infamy, or a public fall from grace. We will attempt to determine whether this is in fact the case, whether there are exceptions to this rule, and if so, when do exceptions occur."
I have this aspect and I did not think it was thaaaaaaaaaat bad.
Her conclusion is that "As is often the case, the truism of “Saturn in the 10th = disaster” is only partly right. It is only the case if Saturn lacks dignity and receives no easy aspects from benefic planets. If you have Saturn dignified in the 10th house with no bad aspects, you can probably relax."
Well, mine is in detriment with both trines and squares. I guess I will have mostly disaster.
This is an interesting writeup on the topic.
"Under Leo, Saturn is brought into the spotlight, into the limelight and is forced into doing something that Saturn abhors generally, and that is being the centre of attention and being “fun”. In analogy, Saturn in Leo is the “old man” who takes to the stage, who acts and is given both fame and fortune. Saturn naturally is alien to the world of glamour, of stars and of attention, so when Saturn is asked by Leo to be “the star”, to show off, to be an individual he responds by doing what he always does: taking it seriously. Leo Saturn must act but is not spontaneous, he must be an individual but at his age, it is a serious thing. The result then is that Saturn looks rather comical in his position, for his placement in Leo is that of being the one that everyone looks up to and wants to be because he is in essence the “hero”, but the way he goes about being hero is matter of fact, duty, and he will save the world, and say at the end “I´m just doing my job”."
