Hello, I have 3 sagittarius placements (sun/moon/pluto) and one scorpio (venus) in my 4th house, can you tell me something about this?
You have a 4th house stellium and a Sagittarius stellium, which implies that you have 3 or more planets in one sign or house.
The strong Sagittarian energy is something I'll talk about first. Sagittarius is often associated with travel, psychology, luck, positivity and freedom. The natal chart of libertarian America has a Sagittarius ascendant: Land of the free, home of the brave. The positivity of Sagittarius is often fragmentary, it's a part of the position but it doesn't mean every Sagittarius is a positive person. In fact, Sagittarians are often positive and empowering towards others, even if they aren't to themselves. They can have steadfast convictions and an unbreakable belief system, especially those who turn to religion (because Jupiter rules religion along with Sagittarius). Sagittarians are often associated to the higher self, the higher mind. These people are always looking for a better self, wanting to improve. They can be bored quickly, whether it's mentally or physically (by activities). The archetype of Sagittarius is the archer. The archer we always refer to was actually a centaur (half horse, half man). Half strength, half wits. Which reiterates their character. Centaurs followed the God Dionysus; God of wine, fertility, fruit, vegetation, insanity, ritual madness, religious ecstasy, festivity and theatre. His religion revolved largely around the consumption of wine. Rather than the drunkenness of it, it revolved on the ease of suffering and the bringing of joy. Performance art and drama were a big part of his religion too. With this info, we can see how he became the symbol of Sagittarius. Sagittarius is ruled by Jupiter, also known as Zeus. Zeus was the son of Cronus, aka Saturn in Roman mythology. Zeus, as we all know, was the God of justice. Sagittarius rules the law. When looking at mythology, we can see where the stereotypical Sagittarian traits came from. Fortune and luck are often bestowed upon Sagittarian positions, but this luck is often only uncovered after the native takes control and change for the better. The reason for this is largely because Jupiter governs over growth, in all areas of life. Change goes hand in hand with this, but the tactics of Sagittarius need to applied as well.
As someone with a Sagittarius Moon, I can definitely confirm that my emotions make me impulsive at times. I've only recently begun to make changes in that aspect. Sagittarius in the Moon is a beautiful placement because of its boundless spectrum of feeling. This can be very overwhelming though. Luckily, the native usually gains some control over this later in life. They're highly ambitious, but tend to get restless (especially when they're falsely accused of something). Zeus was the God of thunder after all, I associate anxiety with this. They have a talent for connecting with their higher self and are always seeking to improve. Furthermore, Sagittarius in Pluto is often seen in detectives. Translators, preachers, prophets, teachers, travelers, actors- all these professions can be linked back to Sagittarius.
Now, Venus in Scorpio. This position is often seen as positive because of the connections to sex and intensity in Scorpio. Thus, having it Venus, the planet of love, is seen as enticing and interesting by many. In fact, Scorpio in Venus people tend to fall hard, not necessarily fast; but hard. There's a tendency for them to get overly obsessed with their crushes and lovers, even to a fault. While the crush phase should be fun and lighthearted butterflies, Scorpio in Venus people tend to see it more as an intense "I want to stare until you forget your own name" phase. Obsession and jealousy are often associated with this position, of course these traits don't apply to everyone- but they are definitely sides of the native's psyche even if they aren't being accessed. They seek a soul-deep romance, which is not to say they can't have flings (depending on mars). A lot of people tend to forget Scorpio is detriment in Venus for a reason; jealousy, secrecy, obsession. All these traits can come out. Positively, though, they're extremely loyal to those they love (if they love-love them). They're quite awkward in the beginning, but they truly worship their lovers. In love, they're usually more the introverted and quietly passionate type. If the relationship is healthy, you have an enticing, loyal, sexual and romantic lover on your hands here. Abandonment is a real knock down here, doesn't matter if it's in a platonic or a romantic relationship. It's not just in romantic love that they love hard, in friendships they do the same. With creative pursuits, they're bound to have some kind of a darker world (art, spiritualism, crime, etc). Once this placement commits, they commit fully. They also love control, which can be manifested positively through leadership. With Venus in the 4th, you need to have some kind of emotional connection to have a relationship with the person. Furthermore, you're likely to be particular about things you like (both sexually and non-sexually).
With all these planets in your 4th house, I'm gonna guess on a couple things here. With all this Sagittarian energy, it could've manifested in multiple ways. You could have a very religious family. Another way it could have manifested is through having parents that were born in different places, have different beliefs/religions, etc. Your Jupiter placements could say a lot about how you dealt with this. For ex. A Jupiter in the 12th with your placements would indicate you breaking the religious bond. There's also the more general indication, maybe your parents moved around a lot. Your emotional happiness, family, ancestry, karma, private self- they are all characterized in the 4th house. In other words, in other to find emotional satisfaction you have to do a lot of higher soul searching through your Sagittarian placements and Scorpio Venus. With all this 4th house energy going on, your home life must've been quite something.
