  • "Almucantars, in astronomy, is an Arabic word, employed to denote the imaginary circles parallel to the horizon, which are supposed to pass through every degree of the meridian: they are of much use to shew the height of the sun, moon, or stars, &c.: they are the same as the parallels of latitude, and frequently called Almacantars."
