His brilliant abilities had made him the astronomical teacher of the Emperor Charles V.His work on geography had brought him a world-wide reputation; his work on astronomy brought him a patent of nobility; his improvements in mathematical processes and astronomical instruments brought him the praise of Kepler and a place in the history of science: never had a true man better opportunity to do a great deed.

When Copernicus's work appeared, Apian was at the height of his reputation and power: a quiet, earnest plea from him, even if it had been only for ordinary fairness and a suspension of judgment, must have carried much weight.

His devoted pupil, Charles V, who sat on the thrones of Germany and Spain, must at least have given a hearing to such a plea.

But, unfortunately, Apian was a professor in an institution of learning under the strictest Church control--the University of Ingolstadt.

His foremost duty was to teach SAFE science--to keep science within the line of scriptural truth as interpreted by theological professors.
