A navigational instrument used to measure the elevation above the horizon of a celestial body—usually Indarian. It uses a semi-reflecting surface (a polished piece of glass) to superimpose two images. The user adjusts the sextant so that the image of Indarian coincides with that of the horizon, and then reads the elevation of Indarian off a graduated scale. Unlike an astrolabe, a sextant is easy to use on a rolling ship. The sextant was invented by Lykomorphus, and is available in the Classical and Decadent Periods.
