Abstract

Anaximander explained the sun as an ejection of light or fire from an opening in the hollow rim of a kind of wheel which revolved around the earth. We are told that this wheel or circle of the sun is 27 times the size of the earth, and again that it is 28 times the size of the earth. These numbers have been thought to represent respectively the inner and the outer diameters of the sun wheel. This has been questioned by Kirk. Kirk assumes that the thickness or width of the rim of the sun wheel would be the same as the diameter of the earth. He argues therefore that there should be a difference of two units between the inner and the outer diameter
