Basics About Jupiter as a Ruling Planet
Jupiter is the largest planet in our solar system. In Western astrology, it traditionally ruled both Sagittarius and Pisces. In modern astrology, however, Jupiter only rules Sagittarius, and Neptune rules Pisces. This article will look at how Jupiter’s influence works for both signs.
The giant planet is associated with luck, optimism, and positivity. The planet is about abundance, expansion, influence, and wealth.

Interesting Tidbits From Roman Times
Rome was first ruled by kings. The monarchy was abolished with the establishment of the Republic. Those suspected of harboring ambitions to revive the monarchy were punished. People deemed as traitors were often executed.
Throughout his reign, King Tullus held hostility toward religion. He wasn’t into religious ceremonies, rites, or piety. Tullus destroyed Alba Longa and deported its inhabitants to Rome. Legend has it that omens followed. Some argued a rain of stones occurred at Alban Mount because the deported Albans didn’t do their ancestral rites linked to Jupiter.
A plague followed and then the king himself got sick. Tullus broke down and gave in to religion. He found a book by King Numa recording a secret rite to summon Jupiter. The king performed the rite, but he did it wrong. Jupiter threw a thunderbolt and it burned down the king's house and killed him.
The Romans took over Jerusalem in a decisive siege starting in AD 70. Aelia Capitolina was established from CE 130-324. A temple to Jupiter Capitolinus was created in the place of the destroyed Temple of Jerusalem.
