Globe with armilary sphere - Nvt - Nvt - late 20th century - Armillary sphere

An armillary sphere is a celestial globe equipped with metal rings that represent the major circles of the sky. The armillary sphere was invented by Eratosthenes in 255 B.C. The name of the instrument comes from Latin, armilla, meaning bracelet. Usually the Earth is placed at the center of the metal rings, but later the Sun as well. The planes of the horizon, the meridian, and the celestial equator are represented by fixed circles. The armillary sphere was designed as an instrument to determine position or time. Renaissance scientists liked to be depicted with an armillary sphere, as a symbol of wisdom and knowledge. In Christian iconography, an armillary sphere is the attribute of Astronomy, one of the Seven Liberal Arts and a symbol of the universe. The instrument is depicted on Portugal’s flag.
