The Early Years: Ancient Observatories

The Sumerians and the Great Observatory of Babylon

The Sumerians, an ancient civilization that thrived in Mesopotamia between 4500 and 1900 BCE, made significant contributions to astronomy. They were among the first to systematically observe the night sky and develop astronomical knowledge. One of their most impressive achievements was the construction of the Great Observatory of Babylon, also known as the Observatory of Marduk.

The exact location of the Great Observatory of Babylon remains unknown, as no physical remains of the structure have been found. However, based on historical records and archaeological evidence, it is believed to have been situated in the city of Babylon, which was the capital of the Babylonian Empire during the reign of King Nebuchadnezzar II (605-562 BCE).

The observatory was a massive structure, consisting of a tower that reached several stories high. The tower’s design was carefully crafted to provide an optimal viewing experience for astronomers, who would use it to observe the stars and planets. The observatory’s orientation was aligned with the celestial bodies, allowing for precise measurements and observations.

The Sumerians were particularly interested in the movements of the planets, especially Venus, which they considered to be a sign of the god Marduk’s divine power. They meticulously recorded the planet’s movements and developed sophisticated algorithms to predict its appearances. The Great Observatory of Babylon played a crucial role in this endeavor, enabling astronomers to make accurate observations and refine their understanding of the planet’s orbit.

The Sumerians also developed a complex system of astrology, which was heavily influenced by their astronomical observations. They believed that the positions of the planets and stars had a direct impact on human lives and events on Earth. As a result, the Great Observatory of Babylon became a hub for divination and fortune-telling, with astrologers using the observatory’s data to make predictions about the future.

The Great Observatory of Babylon served as a model for future observatories in the ancient world. Its legacy can be seen in the architectural design of later observatories, such as the famous Alexandrian observatory in Egypt.

The Egyptian Pyramids and the Construction of the Unas Platform

The construction of the Egyptian pyramids, particularly the Unas Platform, marks an important milestone in the history of observatories. The Unas Platform, named after the pharaoh who built it, is a rectangular stone structure located at the base of the Pyramid of Unas in the ancient city of Saqqara. The platform was built during the Third Dynasty of Egypt, around 2400 BCE, and its purpose was to provide a stable base for the observation of celestial events.

The Unas Platform is an impressive example of ancient Egyptian architecture and engineering. It is made of limestone and granite blocks, and its rectangular shape measures approximately 36 meters by 4 meters. The platform is aligned with the cardinal directions, and its corners are aligned with the solstices and equinoxes. This suggests that the ancient Egyptians had a basic understanding of astronomy and the movement of the sun and stars.

The platform’s main feature is a series of seven holes, which are aligned with the seven celestial bodies known to the ancient Egyptians: the sun, the moon, Mercury, Venus, Mars, Jupiter, and Saturn. Through these holes, the astronomers could observe the movements of these celestial bodies and record their observations in the ancient Egyptian calendar.

The Unas Platform is not the only ancient Egyptian observatory, but it is one of the best preserved. Other examples of ancient Egyptian observatories include the Benben Stone at the Temple of Ra in Heliopolis and the Cairo Observatory, which was built in the 9th century CE. These observatories demonstrate the long history of astronomical observation in Egypt and the importance of astronomy in ancient Egyptian culture.

The Greeks and the Construction of the Aristarchus’s Tower

Aristarchus of Samos was a Greek philosopher and astronomer who lived in the 3rd century BCE. He was one of the first to propose a heliocentric model of the solar system, in which the Sun was at the center and the Earth and other planets orbited around it. To support his theory, Aristarchus proposed the construction of a tower tall enough to observe the movements of the stars and the Sun.

Aristarchus’s tower was to be built on the island of Sicily, and it would have been about 300 feet tall. The tower would have had a series of platforms at different heights, allowing observers to track the movement of the stars and the Sun over time. Aristarchus believed that by studying the movements of the planets, he could determine their orbits and prove his heliocentric theory.

Unfortunately, Aristarchus’s tower was never built, and his ideas were largely ignored by his contemporaries. However, his work laid the foundation for future astronomers and helped pave the way for the construction of more advanced observatories in later centuries.
