Pre-telescopic astronomy

From old times to the seventeenth hundred years, the objective of space science was to depict the developments of divine bodies as precisely as could be expected.

Seen with the unaided eye: stars and planets with the sun and moon. The universe was restricted to planetary circles and the circle of fixed stars – the Earth involved a unique spot in it. In ancient times, the division of space science into two patterns was obviously noticeable: viable, for example connected with the necessities of regular daily existence, and logical – zeroing in on the development of numerical models that would permit to exactly depict the developments of the planets in the divine circle and foresee their future positions. The main pattern was transcendent in Egypt, the second – in Greece; Ancient Mesopotamian space science was a combination of both.

Stargazing of Ancient Egypt and Mesopotamia

The most persevering through accomplishments of old Egyptian cosmology were the presentation as soon as around 3000 BCE. a schedule in light of a 365-day year and the division of the evening and afterward the day into 12 sections, from which our 24-hour day at last came from.

In antiquated Mesopotamia, the Sumerians – who are credited with developing not long before 3000 B.C. cuneiform composition with a pointer on mud tablets – added to stargazing by giving the heavenly bodies names, some of which have made due to the current day, for instance Taurus, Leo and Scorpio (see old Mesopotamian heavenly bodies). The earliest Babylonian galactic texts date from the turn of the eighteenth/seventeenth hundreds of years B.C.E. – the most established landmark is the mysterious abridgment “Enuma Anu Enlil”, containing data about the positions and times of Venus perceivability. The last celestial chronological registry in this custom traces all the way back to AD 75 and was tracked down in a sanctuary in Babylon. The advancement of stargazing in Mesopotamia was firmly connected with the extraordinary job of crystal gazing in friendly and political life, albeit the main logical accomplishments went a long ways past the restrictions of applied soothsaying.

We owe Babylonian stargazing the presentation of the zodiac (around the fifth century BC), both as a bunch of heavenly bodies and as an extraordinary circle, which is the premise of an ecliptic coordinate framework on the divine circle. From the neighborhood computational custom, the degree – as the essential unit of rakish estimation – and the sexagesimal framework come from. Notwithstanding texts wealthy in data about noticed cosmic peculiarities (for example a rundown of obscurations tracing all the way back to the center of the eighth century B.C.E.), Babylonian cosmology abandoned painstakingly characterized major boundaries, for example, the synodal month, the tropical year, and the connections between planetary cycles. Around 500 B.C.E. in Babylonian space science, numerical models created the impression that made it conceivable to compute – based on created calculations and utilizing a few decided boundaries – the hour of event of significant galactic peculiarities: new and full moon, shrouds, times of planets’ perceivability, their resistances and positions.
