John Russell's 'Selenographia'

The name 'Selenographia' refers to the complete assembly of a lunar globe engraved by John Russell, RA, together with a mechanical stand designed by the artist himself. The graduated scales and the variety of rack and pinion adjustments on the brass stand permit a demonstration of the various elements of the moon's oscillatory 'libration', while the small earth globe can be used to demonstrate parallax. In order to do this, the earth globe has to be very small because its distance from the moon is so greatly contracted.

A large pastel drawing of the moon by John Russell can be seen on the Museum staircase.
