Tracking the Skies: Observing the Planets in Antiquity

Observing celestial bodies has been part of human civilization since ancient times. Studying the night sky, early civilizations were able to create calendars, tell time, navigate seas, and even make early scientific breakthroughs. Spoken of in literature, etched into rocky surfaces, and passed down through generations, the observation of the planets in antiquity and their influence on ancient societies cannot be understated.

The Ancient’s Astronomical Toolkit

Living amid nature’s vastness, ancient astronomers lacked the sophisticated telescopes and programmed technology we take for granted today. Instead, they relied on pure observation, detailed recordkeeping and calculated predictions.

1. Visual Observation: With their naked eyes, they keenly observed the night sky, distinguishing celestial bodies based on brightness, color, and movement.
2. Ancient Devices: They produced early astronomical instruments, such as the sophisticated antikythera mechanism, the simple astrolabe, or the complex armillary sphere.
3. Mathematical Knowledge: Ancient Greeks were able to calculate the Earth’s circumference using the geometry of shadows. They also developed sophisticated algorithms to predict the movement of celestial bodies.

Distinguishing Planets from Stars

Observing the night sky poses an interesting challenge: distinguishing stars from planets. Ancients noticed that certain celestial objects did not maintain their fixed positions among the stars, instead appearing wandering stars, or what we now term planets.

The Five Visible Planets and Their Greek Namesakes

The five visible planets - Mercury, Venus, Mars, Jupiter, and Saturn - were all identified and tracked by ancient civilisations. Each one was given a name based on its characteristics or the deity it was thought to represent.

1. Mercury: Known to be elusive, seen mainly at twilight. Greeks called it Hermes, the quick and cunning messenger of the gods.
2. Venus: Its bright light meant it was often mistaken for a star. Named Aphrodite by the Greeks, the goddess of love and beauty.
3. Mars: Its reddish tint earned it the name Ares, the fiery god of war.
4. Jupiter: The brilliant Jupiter was named after Zeus, the ruler of the gods.
5. Saturn: Named Kronos by the Greeks, the father of Zeus, it stood out due to its slow movement.

Ancient Astronomical Giant - Mayan Civilization

Among Ancient cultures, the Mayan civilization shines brilliantly in their astronomical achievements. Able to accurately predict lunar and solar eclipses, they also traced the path of Venus so well that their calculations differ by just 2 hours from modern calculations. They had even built impressive observatories, such as the Caracol at Chichen Itza, resembling modern-day observatories.

Our ancestors’ astronomy skills are a testament to mankind’s enduring curiosity and thirst for knowledge, epitomizing the innate human quest to understand our place in the universe. As we continue to advance in our astronomical pursuits, remember the observation of the planets in antiquity and the insatiable curiosity by which our ancestors viewed the universe.

After all, as Sagan once so eloquently put it, we are all made of starstuff.
