Book Description
First edition (1851) and the rarest of Hay's books. The Scot David Ramsay Hay (1798-1866) is best known through his many books on colour theory. He was a successful house decorator, counting Sir Walter Scott and Queen Victoria amongst his clients. Here he tackles with much gusto and energy the age old problem of proportion. His system of proportion is based upon the harmonic ratios of the diatonic scale: 'the eye is influenced, in its estimations of spaces, by a simplicity of proportions similar to that which guides the ear in its appreciation of sounds'. 'The basis of the present theory, therefore, simply is, that a figure is pleasing to the eye in the same degree as its fundamental angles bear to each other the same proportions that the vibrations bear to one another in the common chord of music'. The plates are 'representing geometric constructions and illustrations of the male and female skeletons, and muscle manikins, with the lines of proportion, after Hay's system. They are all drawn by the author and beautifully engraved by W. Forrest.

Book Description
Aristotle believed that the outermost stars are carried round us on a transparent sphere. There are directions in the universe and a preferred direction of rotation. The sun moon and planets are carried on different revolving spheres. The spheres and celestial bodies are composed of an everlasting fifth element, which has none of the ordinary contrary properties like heat and cold which could destroy it, but only the facility for uniform rotation. But this creates problems as to how the heavenly bodies create light, and, in the case of the sun, heat. The value of Simplicius' commentary on On the Heavens 2,1-9 lies both in its preservation of the lost comments of Alexander and in Simplicius' controversy with him. The two of them discuss not only the problem mentioned, but also whether soul and nature move the spheres as two distinct forces or as one. Alexander appears to have simplified Aristotle's system of 55 spheres down to seven, and some hints may be gleaned as to whether, simplifying further, he thinks there are seven ultimate movers, or only one.
