'The first to form any definite idea as to the constitution of the stellar system was Thomas Wright, the son of a 

 carpenter living at Byer's Green, near Dm ham. With hitn originated what has been called the 'Grindstone Theory' of 

 the universe, which regarded the Milky Way as the projection on the sphere of a stratum or disc of stars (our sun 

 occupying a position near the centre), similar in magnitude and distribution to the lucid orbs of the constellations.' — 

 Miss A. M. CUrke. 



The work moreover contains the first definite suggestion that Siturn's ring consisted of a multitude of unconnected 

 particles, each revolving independently round the planet. J. Clerk Maxwell in 1857 demonstrated this as the only 

 scientifically tenable theory against the hypotheses of solid or fluid rings.
