This large tellurian is a very grand scientific instrument that provides a way to visualise the earth's relationship to the sun and the moon. The sun is represented by a candle which when lit reflects on a mirrored surface onto the globe. A geared mechanism allows the moon to spin around the earth, which in turn spins around the sun. The tellurian has a seven-inch terrestrial globe, which allows for a certain amount of details, particularly physical features. The ocean currents, mountain ranges and rivers are depicted and some political borders are marked. The globe is attached to a bronze arm that rests on a decorative base. The round base on which the elaborate candleholder sits has concentric circles representing the months of the year, seasons, zodiac signs and directional points.
