Astronomical model, lantern slide, wood / glass / metal, made by Dollond, London, England, 1750-1850 Model in a rectangular wooden frame with a circular painted glass plate in the middle displaying a day and night astronomical cycle in a brass frame. Light shines through the plates and illuminates the model. The bass frame has teeth around its edge, allowing it to be turned by a gear handle. The glass has two sets of the numbers '3, 6, 9, 12' in a circular form around a map of the world divided into images of day and night with the sun in blue and the moon amongst clouds with a dark paint. There is a brass handle for gearing that makes the world spin within the numbers that are around it. The model is designed to show the astronomical phenomena by transmitted light.
