Medieval flat star chart
The star chart is an ancient astronomical instrument, which can be said to be a handheld model of the universe. Its various functions also make it a sophisticated inclinometer and an analog computing device capable of solving several problems in astronomy. In its simplest form, it is a metal disk with patterns of wires, cuts, and perforations, allowing users to accurately calculate the position of celestial bodies. Astronomers throughout history have used it to measure the height of celestial bodies on the horizon, both during the day and at night; It can be used to identify stars or planets, determine the local latitude at a given local time, measure or conduct triangulation.
