A sextant is a navigational instrument used to measure the angle between an astronomical object and the horizon, allowing sailors to determine their latitude and longitude at sea The sextant had to be pointed downward to view the reflection of the celestial body on the surface of the mercury pool through the clear portion of the horizon glass while simultaneously adjusting the index system to bring the image reflected by the two mirrors alongside. This invention was crucial for improving maritime navigation during the age of exploration, connecting it with the rapid technological innovations occurring between 1450 and 1750.
