Question

In the introduction to his book Great Astronomers, Robert Stawell Ball states, “The history of astronomy thus becomes inseparable from the history of the great men to whose labours its development is due.” Based on what you read in the Ptolemy section, how does Ball develop and refine this central idea in his book?

Answer 1

What do you mean by "what you read in the Ptolemy section" though? Is this a specified excerpt or a theme that you're being asked to discuss?
