This is a beautiful solid brass decorative antique reproduction of an Astronomical Armillary. This decorative reproduction of a astronomical armillary includes the names of the 12 astrological signs engraved into the globe in Arabic letters. The concentric rings, which rotate 360 degrees and are held together on a center axis, are intricately engraved with the signs of the Zodiac and are printed with the Zodiacís Arabic name on the outer rim. The armillary is made from solid brass, not brass-plated steel, and hangs from two suspension loops. It has a rich antique patina which will not tarnish nor show fingerprints. The Astronomical Armillaryís largest ring measures 13.5 inches (34.3 cm) in diameter, 17 inches (43.2 cm) tall, and the center hollow globe sphere is 4 inches in diameter (10.2 cm). The Astronomical Armillary is very heavy weighing 6 pounds, 13 ounces (3.1 kg) and is suitable for hanging from a shelf or a ceiling.
