The first astrological house is an angular house. This is the native to the zodiac Ares and is ruled by Mars. The element associated with the first house is fire. The first house is the house of self and where we can find the ascendant. The ascendant in a natal chart is the sign that was rising on the horizon during the time of birth, and it directs a person’s life path.
Planets in the first house attribute to your personality, and your first impression of others. The sign rising creates the overall mask of who you are. The element of the rising sign is the element you present to the world first. For example, if you have an earth sign in the rising sign, then your go-to element is earth. Your personality would be defined as practical, down to earth, you are seen as a sensual person, material stability and luxury are essential for you. I’ll continue on with the elements in the rising… If the sign of your rising is a fire sign then you are more inclined with being self-centered (this is not all bad), vibrant, possibility temperamental, having a child-like wonder and air, personal freedom is one of your focus.
With a water sign as the rising, you’ll have a knack for understanding and manipulating other’s emotions, you can reflect what others feel back to them if need be. Security is prominent in your life, your mother and family will have a significant impact on your personality. For air signs as the rising your personality focus on mental aspects, relationships and communicating with others are essential. Being social is a must. These rising are logic centered and are more inclined to explore social boundaries.
As for the Personal Planets in the 1st house. It is like having a Sun, Moon, Mercury, Venus, or Mars conjunct with Mars. The Planets become lord of your chart and aspects you closely identify with. Sun in the 1st house is for leaders though who will not allow anyone else put out there shine. They are conscious of what others see of them and their first impression. Sun here is like an Aries sun. My advice to allow them to be them. Getting in their way will be a mistake.
With the Moon here, your emotions are apparent, woman and your mother are important influencers for good or bad in your life. This is close to having an Aries moon or a Moon/Mars conjunction. Someone with the moon in the first house is likely to have a bit of a temper, combative, or someone who leads their life with emotions or a mother who is like that. You can reflect what others feel with this placement. The closer the moon is to the ascendant the more prevalent this is.
Mercury here leads you to be talkative and a smarty pants. Someone with this placement will have a quick mind and a sharp tongue with multiple interests and skills. Though because this is like having a Mercury/Mars conjunction it makes you ruthless when in an argument. I personally would not want trade words with this person.
Venus here makes some level of your personality diplomatic. You can be physically attractive in some way, or artistically inclined. This planet allows balance in the native life and nature. Favorable, because Venus is about money, situations flow into this Persons life. This is relatable to having Venus/Mar conjunction possibly making someone passive aggressive.
Mars in comfortable here. This is one of the best places for Mars. The planet makes you active here, giving you the energy to stand up for yourself. This makes you act bolder than any other planet, except for the Sun. Most people with Mars in the first require physical exertion like running, jogging, weight lifting, martial arts, etc. The closer Mars is to the ascendant the stronger its influence on the native’s personality.
