Astronomy in the past
Astronomy (the meaning, in Greek, of the word, is "law of the stars") is one of the oldest science, its beginnings dating back to prehistoric times, when people were concerned with observing nature to understand the meaning of stars, eclipses, tides, seasons etc.
Benefiting from the dark sky, ancient people could see the stars appear in the eastern part of the sky, moving upwards and setting to the west. In one direction, the stars moved in small circles.
Nowadays, when we look at the north, we see in that position a star - the North Star or Polaris. This is not a very bright star: there are 48 stars in the sky that are brighter than it, but by chance, the North Star is in an interesting place. In ancient times other stars were aligned with the north pole of the Earth or sometimes there were no stars in the vicinity of the north pole.
Because people could look at the sky very often, they noticed that there were some brighter bodies, reduced in number and not rising and not setting exactly like the stars. Of course, the Moon was by far the brightest object in the night sky. The moon rose almost an hour late every night and, in time, appeared with other different stars behind it. Also, over time its shape also changes being visible, what we now call the phases of the Moon.

Lascaux Cave painting
The first discoveries
in ancient times
Various calculations on the phenomenon of the new moon were discovered on eagle bones, preserved in caves, dating back 32,000 years, and drawings over 17,000 years old were identified in the Lascaux cave, in France. This demonstrates knowledge of rudimentary astronomy, a kind of representation of the Pleiades (bright stars in the constellation Taurus, observable in the northern hemisphere) and the zodiac (the twelve constellations, which the Sun crosses over a year). It is not known the exact significance of these images on the cave walls, but it could be one of a religious nature or, perhaps, the representation of a calendar, marking the period of great migrations, hunting, etc.
Discoveries
The Gosek Circle
The Gosek Circle, discovered in 2003 in Germany, dating from the Neolithic (7000 years ago) seems to be one of the oldest "astronomical observatories".
It has the shape of concentric circles, with a diameter of 75 meters, with three openings corresponding to the sunrises and sunsets, at the winter and summer solstice.

Ancient Egypt
The representation of the starry sky was made, in antiquity, on the cupola of the Egyptian pyramids. The interpretations of scholars in ancient Egypt brought together elements of astronomy and astrology: the year was 365 days, and the repeated overflows of the Nile were related to the star Sirius (the brightest star seen on Earth, apart from the Sun), to which Thebes Celebrations were consecrated .
Like other ancient peoples, they used stellar configurations to explain certain important events, especially the rebirth of the human spirit and the Pharaoh in particular. The Egyptians attached great importance to this process by which they believed that the Pharaoh would join the gods after he rose and ascended to heaven. This resurrection was closely related to the star Sirius and its motion in the sky.
