I'm interested in some ancient prototypes of telescopes.I know that antient tribes and empires were particularly dependent and believed in horoscopes and astrology. So I wish to know what device (probably the great-grandfather of telescope) they used to observe space! THANK YOU!!!

Most ancient observations of the heavens were made to measure precise locations of stars and to determine the exact timing of events such as rise and set and especially when they crossed the Meridian.
(Astrology was an offshoot of Astronomy to help the ancients to make sense of some of the unexplainable things happening to them. It is a belief system, not a science)
Observatories in the ancient times included Quadrants, Meridian circles and Astrolabes. All of these were devices used with the naked eye.
It is amazing how accurate these old Astronomers could be and how precise some of these measurements were. The "Hipparcus" catalog was used as the basis for most positional information well into the 1800's. It's system for rating a star's magnitude or brightness is still in use today, with only slight modifications.
There is a new Hipparcus catalog named after the old greek fellow which was compiled recently.
Do a google search for "Ancient Observatories" and you will find a good number of them with some excellent images to show you what the equipment looks like.
BTW, the Sextant which is derived from these ancient observing tools was until just a few years ago the primary tool for navigation at sea and was just recently replaced by GPS.
I stiil keep my Sextant aboard at all times as a back-up instruments. ( It has no batteries that can fail, and supermarkets are few and far between out at sea )

The first telescope patent was applied for by a dutch spectacle-maker named Hans Lippershey in 1608, though evidence suggests others may have come up with similar instruments around the same time. Galileo was the first to publish an account of astronomical observations using the telescope.

For many centuries before the invention of the telescope, astronomical measurements were made with a variety of naked-eye sighting instruments. The first astronomical instrument, by some accounts, was the Egyptian merkhet. This was basically a notched stick with a plumb bob attached. Other early astronomical instruments include the astrolabe, the armillary sphere, and the quadrant.

Galileo, in 1609, used his telescope to discover the four largest satellites of Jupiter and that they rotate around Jupiter.
They are now called the Galilean satellites of Jupiter.

His was probably not the first, by a few years, but probably the second telescope.

But he was the first to use it to the fullest extent possible for astronomy.
