Description
A fine example of a tellurian, an instrument to demonstrate: the movement of the Earth around the Sun; how the seasons result from the tilt of the earth; how the Earth's rotation on its axis cause night and day; and the waxing and waning of both the Moon and Venus. The base is graduated to show the seasons, months and the Zodiac.
