display model with sun, earth and moon on heavy, silver lacquered cast metal base.
this planetary model can be used to illustrate the positions of the heavenly bodies at different times of the year, the phases of the moon, the tides and during solar and lunar eclipses.

above the rotating axis of the stand is a disc on which the seasons, the signs of the zodiac and the exact date can be read. In the centre of the calendar is a candle holder. The light from the candle is projected - impressively accurately - like a sunbeam onto the globe via a concave mirror. This can be clearly seen in the attached video, which shows a tellurium of the same design.

the tellurium is set in motion with a hand crank. Thus the earth rotates around itself, the moon around the earth and moon and earth around the sun. In addition, in the course of a "year", i.e. One revolution around the sun, the inclination of the earth changes. The four seasons can be explained from this inclination of the earth.

the calendar disc is marked in the centre: fr. J. Berg stockholm
the earth globe is inscribed: jord glob stockholm

condition:
the tellurium was completely disassembled, cleaned and overhauled by the clockmaker. The mechanism works perfectly. The calendar disk and globe are in good condition with slight signs of wear due to age. The original silver paintwork has been preserved. See less
