Science in its infancy found many powerful opponents, who, not understanding the nature of the newly-born babe, strove to strangle it. But the infant grew into a healthy child in spite of its cruel stepmother, and cried so loudly and talked so strangely that the world was forced to listen to its utterances. These were regarded with distrust and aversion by the theologians of the day, for they were supposed to be in opposition to Revelation, and contrary to the received opinions of all learned and pious people. Therefore Science met with very severe treatment; its followers were persecuted with relentless vehemence, and "blasphemous fables" and "dangerous deceits" were the only epithets which could characterise its doctrines.

The controversy between Religion and Science still rages, in spite of the declaration of Professor Huxley that in his opinion the conflict between the two is entirely factitious. But theologians are wiser now than they were in the days of Galileo; they are waiting to see what the scientists can prove, and then, when the various hypotheses are shown to be true, it will be time enough to reconcile the verities of the Faith with the facts of Science.

To those who believed that the earth was flat it was somewhat startling to be told that there were antipodes. This elementary truth of cosmology Bishop Virgil of Salzbourg was courageous enough to assert as early as A.D. 764. He wrote a book in which he stated that men of another race, not sprung from Adam, lived in the world beneath our feet. This work aroused the anger of Pope Zacharias II, who wrote to the King of Bavaria that Virgil should be expelled from the temple of God and the Church, and deprived of God and the Church, and deprived of his office, unless he confessed his perverse errors. In spite of the censure and sentence of excommunication pronounced upon him, Bishop Virgil was canonised by Pope Gregory XI.; thus, in spite of his misfortunes brought about by his book, his memory was revered and honoured by the Western Church.

If the account of his imprisonment be true (of which there is no contemporary evidence) our own celebrated English philosopher, Roger Bacon, is one of the earliest scientific authors whose works proved fatal to them. In 1267 he sent his book, Opus Majus, together with his Opus Minus, an abridgement of his former work, to Pope Clement IV. After the death of that Pope Bacon was cited by the General of the Franciscan order, to which he belonged, to appear before his judges at Paris, where he was condemned to imprisonment. He is said to have languished in the dungeon fourteen years, and, worn out by his sufferings, to have died in his beloved Oxford during the year of his release, 1292. The charge of magic was freely brought against him. His great work, which has been termed "the Encyclopaedia and the Novum Organum of the thirteenth century," discloses an unfettered mind and judgment far in advance of the spirit of the age in which he lived. In addition to this he wrote Compendium Philosophiae, De mirabili Potestate artis et naturae, Specula mathematica, Speculum alchemicum, and other works.

The treatment which Galileo received at the hands of the ecclesiastics of his day is well known. This father of experimental philosophy was born at Pisa in 1564, and at the age of twenty-four years, through the favour of the Medicis, was elected Professor of Mathematics at the University of the same town. Resigning his chair in 1592, he became professor at Padua, and then at Florence. He startled the world by the publication of his first book, Sidereus Nuntius, in which he disclosed his important astronomical discoveries, amongst others the satellites of Jupiter and the spots on the sun. This directed the attention of the Inquisition to his labours, but in 1632 he published his immortal work Dialogo sopra i due Massimi Sistemi del monda, Tolemaico et Copernicano (Florence), which was the cause of his undoing. In this book he defended the opinion of Copernicus concerning the motion of the earth round the sun, which was supposed by the theologians of the day to be an opinion opposed to the teaching of Holy Scripture and subversive of all truth. The work was brought before the Inquisition at Rome, and condemned by the order of Pope Urban VIII. Galileo was commanded to renounce his theory, but this he refused to do, and was cast into prison. "Are these then my judges?" he exclaimed when he was returning from the presence of the Inquisitors, whose ignorance astonished him. There he remained for five long years; until at length, wearied by his confinement, the squalor of the prison, and by his increasing years, he consented to recant his "heresy," and regained his liberty. The old man lost his sight at seventy-four years of age, and died four years later in 1642. In addition to the work which caused him so great misfortunes he published Discorso e Demonstr. interna alle due nuove Scienze, Delia Scienza Meccanica (1649), Tractato della Sfera (1655); and the telescope, the isochronism of the vibrations of the pendulum, the hydrostatic balance, the thermometer, were all invented by this great leader of astronomical and scientific discoverers. Many other discoveries might have been added to these, had not his widow submitted the sage's MSS. to her confessor, who ruthlessly destroyed all that he considered unfit for publication. Possibly he was not the best judge of such matters!

Italy also produced another unhappy philosophic writer, Jordano Bruno, who lived about the same time as Galileo, and was born at Nole in 1550, being fourteen years his senior. At an early age he acquired a great love of study and a thirst for knowledge. The Renaissance and the revival of learning had opened wide the gates of knowledge, and there were many eager faces crowding around the doors, many longing to enter the fair Paradise and explore the far-extending vistas which met their gaze. It was an age of anxious and eager inquiry; the torpor of the last centuries had passed away; and a new world of discovery, with spring-like freshness, dawned upon the sight. Jordano Bruno was one of these zealous students of the sixteenth century. We see him first in a Dominican convent, but the old-world scholasticism had no charms for him. The narrow groove of the cloister was irksome to his freedom-loving soul. He cast off his monkish garb, and wandered through Europe as a knight-errant of philosophy, multum ille et terris jactatus et alto, teaching letters. In 1580 we find him at Geneva conferring with Calvin and Beza, but Calvinism did not commend itself to his philosophic mind. Thence he journeyed to Paris, where in 1582 he produced one of his more important works, De umbris idearum. Soon afterwards he came to London, where he became the intimate friend of Sir Philip Sidney. Here he wrote the work which proved fatal to him, entitled Spaccio della bestia triomphante (The expulsion of the triumphing beast) (London, 1584). [Footnote: The full title of the work is: Spaccio della bestia triomphante da giove, effetuato dal conseglo, revelato da Mercurio, recitato da sofia, udito da saulino, registrato dal nolano, divisa in tre dialogi, subdivisi in tre parti. In Parigi, 1584, in-8.] This was an allegory in which he combated superstition and satirised the errors of Rome. But in this work Bruno fell into grievous errors and dangerous atheistic deceits. He scoffed at the worship of God, declared that the books of the sacred canon were merely dreams, that Moses worked his wonders by magical art, and blasphemed the Saviour. Bruno furnished another example of those whose faith, having been at one time forced to accept dogmas bred of superstition, has been weakened and altogether destroyed when they have perceived the falseness and fallibility of that which before they deemed infallible.

But in spite of these errors Bruno's learning was remarkable. He had an extensive knowledge of all sciences. From England he went to Germany, and lectured at Wittenberg, Prague, and Frankfort. His philosophy resembled that of Spinosa. He taught that God is the substance and life of all things, and that the universe is an immense animal, of which God is the soul.

At length he had the imprudence to return to Italy, and became a teacher at Padua. At Venice he was arrested by order of the Inquisition in 1595, and conducted to Rome, where, after an imprisonment of two years, in order that he might be punished as gently as possible without the shedding of blood, he was sentenced to be burned alive. With a courage worthy of a philosopher, he exclaimed to his merciless judges, "You pronounce sentence upon me with greater fear than I receive it." Bruno's other great works were Della causa, principio e uno (1584), De infinito universo et mundis (1584), De monade numero et figura (Francfort, 1591).
