Astronomers who went on the Ptolemaic theory managed to provide a very fair description of the actual phenomena of the heavens; but the solid result of their labors was not lost when the Copernican system took its place; and incalculable advantages followed from casting aside the old cumbrous machinery of cycles and epicycles in favor of the simpler conceptions of the new doctrine.
He had known Bruno, had attended many of his lectures, and had followed his career with interest; and while he agreed with him concerning the Copernican theory of the earth's revolution, he took exceptions to Bruno's arbitrary ways of presenting the matter, and also to his scathing criticisms of theology.
But when Leverrier by means of the data of this system not only discovered the existence of a certain unknown planet, but even calculated the position in the heavens which this planet must necessarily occupy, and when Galles really found this planet, then the Copernican system was proved.
In the adjoining figure we represent a portion of the circular tracks in which the earth and Mars move in accordance with the Copernican doctrine. Mars is then advancing in the direction shown by the arrow-head, and the earth is also advancing in the same direction.
Galileo's proof of the Copernican theory marked the downfall of mediævalism and established astronomy on a firm foundation. But while his telescope multiplied a hundredfold the number of visible stars, more than a century elapsed before the true possibilities of sidereal astronomy were perceived.
Galileo treats his opponents with severity and sarcasm He is aided by the sceptics of the day The Church party the most powerful Galileo commences the attack, and is answered by Caccini, a Dominican Galileo's Letter to the Grand Duchess of Tuscany, in support of the motion of the Earth and the stability of the Sun Galileo visits Rome Is summoned before the Inquisition, and renounces his opinions as heretical The Inquisition denounces the Copernican System Galileo has an audience of the Pope, but still maintains his opinions in private society Proposes to find out the Longitude at Sea by means of Jupiter's Satellites His negociation on this subject with the Court of Spain Its failure He is unable to observe the three Comets of 1618, but is involved in the controversy to which they gave rise.
Darwin's hypothesis is not, so far as I am aware, inconsistent with any known biological fact; on the contrary, if admitted, the facts of Development, of Comparative Anatomy, of Geographical Distribution, and of Palaeontology, become connected together, and exhibit a meaning such as they never possessed before; and I, for one, am fully convinced, that if not precisely true, that hypothesis is as near an approximation to the truth as, for example, the Copernican hypothesis was to the true theory of the planetary motions.
When, therefore, the Copernican astronomy proved true, when the first terrific shock of it had passed through resultant anger into wonder and from wonder into stupefied acceptance, and from that at last into amazed exultation at the vast, new universe unveiled, the credit of antiquity received a stunning blow.
It is, indeed, not a little remarkable that a student of the heavens so accurate as Tycho should have deliberately rejected the Copernican doctrine in favour of the system which now seems so preposterous.
He was, as has been said, a vorticist before Descartes, an optimist before Leibnitz, a Copernican before Galileo. It would be easy to collect a hundred strange opinions of his. He was born about 1550, and was roasted alive at Rome, February 17, 1600, for the maintenance and defence of the Holy Church, and the rights and liberties of the same."
