Total length 65cm, total height 25cm. Rare Hawkes tellurium of approx. 1925. These telluriumís are rare complete. A wooden column supports a large 16cm brass sphere representing the sun with Venus circling the sun, from which extends a 43cm aluminium arm supporting a terrestrial 10cm (4inch) terrestrial globe with moon. The globe is made by the George F. Cram co Indianapolis U.S.A. As the arm swings, the mechanical gears move the earth, moon and Venus. Everything functions well. The arm has an inset compass. So Venus circles the sun. The earth circles the sun, circles around its own axis and circles towards and from the sun according to the seasons. The month of the year is shown on the base just beneath the sun. The moon circles the earth and the cap on the moon is always turned towards the sun. This model can be used to explain the seasons, day and night, phases of the moon, solar eclipse, lunar eclipse etc.
