|Paper, 'The description of a celestiall globe, artifically made, showing the apparent motions, from east to west, and from west to east, of the Sun, Moon, and fixed stars' by Didier L'Alleman
|L'Alleman describes a 'celestial globe' which has been designed using the observations of 'the most famous astronomers of this age. L'Alleman was a master watchmaker in Paris. He states that 'philosophers have been labouring for many years to decide by some experience, whether the action of light be conveyed in an instance to distant places, or whether it requires time.'
