An astronomical instrument is a device for observing, measuring or recording astronomical data. They are used in the scientific field of astronomy , a natural science that studies celestial objects and the phenomena that occur in the cosmos, with the object of explaining their origin and evolution over time.
The ship carrying the device contained vases in the Rhodian style, leading to a hypothesis that it was constructed at an academy founded by Stoic philosopher Posidonius on that Greek island. [47] Rhodes was a busy trading port and centre of astronomy and mechanical engineering, home to astronomer Hipparchus, who was active from about 140–120 BC.

An astrolabe (Ancient Greek: ἀστρολάβος astrolábos, ' star-taker '; Arabic: ٱلأَسْطُرلاب al-Asṭurlāb; Persian: ستارهیاب Setāreyāb) is an astronomical instrument dating to ancient times. It serves as a star chart and physical model of visible half-dome of the sky.
The Antikythera mechanism was an analog computer from 150–100 BCE designed to calculate the positions of astronomical objects. Ancient Greek astronomy is the astronomy written in the Greek language during classical antiquity. Greek astronomy is understood to include the Ancient Greek, Hellenistic, Greco-Roman, and late antique eras.
Parts of the instrument go back to instruments made and used by ancient Greek astronomers. Gemma Frisius combined several of the instruments into a small, portable, astronomical-ring instrument. He first published the design in 1534, [2] and in Petrus Apianus's Cosmographia in 1539. These ring instruments combined terrestrial and celestial ...
The roots of the equatorium lie in the astrolabe.The history of the astrolabe dates back to roughly 220 BC in the works of Hipparchus. [6] The difference between the two instruments is that the astrolabe measures the time and position of the sun and stars at a specific location in time. [7]
