Multiple identical constellations appear in the astrolabe.

In some people's astrolabes, planets will gather together, such as several planets in the same constellation, or several planets in the same house, more than other constellations or houses.

Every planet, every house and every constellation has its own energy. When planets gather in a constellation, it means that the energy characteristics of the constellation are very strong.

For example, the star Pisces, even if you are the sun Capricorn, the stars are all in Pisces, and your Pisces energy will overwhelm your sun sign, which will have a particularly deep impact on you. You will show strong Pisces characteristics, such as being confused, fond of dreaming, soft-hearted, compassionate, loving cats and dogs, flowers and plants, and being particularly easily moved, tearful and spiritual.

So is the house. If there is a planet in one house in your chart, then you are very talented in the field represented by this house, and you can easily do it. Of course, your lessons in this field are stronger on you.
