In modern common knowledge, the Solar System had nine major planets. In order of distance from the Sun, they were Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.
However, in the Middle Ages, especially before heliocentrism became widespread, the seven planets referred to the seven celestial bodies of medieval astrology: the Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn.
Astrologers after Ptolemy believed that each planet was fundamentally a mixture of two attributes.
The Sun's active energy was heat, along with a certain degree of dryness.
Most of the Moon's energy consisted of coldness and moisture.
Saturn's attributes were mainly coldness, with moderate dryness.
Mars's nature was mainly dryness and burning.
Jupiter was both hot and moist. Although it was not as hot as Mars or the Sun, it had more heat than moisture.
Venus possessed the same energy and mild, moderate nature as Jupiter, but in the opposite way.
Ptolemy was a famous wizard. He even had a Chocolate Frog card.
He was a mathematician, astronomer, geographer, and astrologer. If the labyrinth around the altar really was the planetary orbit Voldemort had described, then it would not be easy to figure out.
Ancient people observed the stars by treating the sky as a sphere, with the stars moving across its surface. Observers used astrolabes for astronomical measurements.
An astrolabe could be used to locate and predict the positions of the Sun, Moon, Venus, Mars, and other celestial bodies.
The Sun represented the self, the Moon represented women, Mercury represented thought, Venus represented harmony, and so on.
The drunkard had entered the labyrinth without incident, perhaps because he had not triggered its defensive magic at all. But the two of them were trying to retrieve Sun Gold—assuming it was really inside. That ancient alchemist was not like Pomona,
