After the age of trace out more accurately the exact curves in which the planets Ptolemy little progress appears to have been made, and even moved, and to ascertain their various distances, sizes, and rates known truths were to a great extent forgotten.

He was of Danish extraction, and was born very shortly after After the fall of the Roman empire the science found a home the death of Copernicus. It is said that his attention was first among the Arabians, who, in the eighth century, seem to have directed to the science of astronomy by an eclipse which dovoted much attention to its study, and to have made con happened at the time predicted, in the year 1560, and incited siderable advances in it.

In this way he continued in a large orbit, he thought the fixed stars ought to appear in a to try one hypothesis after another, submitting each to the test different position when seen from one extremity of the orbit to of most careful observation, till at length no fewer than nineteen that which they occupied when seen from the other extremity; different theories had been proposed, and the movements of the and not being able to observe this change, he concluded that the planets compared with those which were calculated by these earth must be at rest. The principle of this argument was theories;

The reason why it is not important negative result he had, however, arrived at, and this more clearly seen is that, great as is the diameter of the earth's was that, whatever was the nature of the curve the planeta orbit, the distance of even the nearest fixed star is so immensely described, it was not a circle, nor a combination of circles. This greater that the change produced is scarcely visible. We may was one great step towards the solution of the task. From the notice this same effect as we are carried rapidly along in a train; very earliest ages it had been assumed that, as the circle the objects situated near to the line of railway seem to move seemed the perfection of form, all the heavenly bodies must more past us very rapidly, those further off have a less apparent in circles; but Kepler now cast off this trammel, and then speed, while lofty objects in the distance scarcely seem to move applied himself afresh to his task. at all.
