He was the first who dared to dispute the words of Galen and point out his errors,—to ascertain that the greater part of Galen's descriptions, having been made from monkeys, did not correctly represent human anatomy. This audacity raised a crowd of vehement opponents, the least reasonable and most fanatic being his old master, Sylvius; but even these onslaughts could not conceal the truth. The minds of men generally were ripe for the revolution whose signal-fire was thus lighted, and no sooner did Vesalius appeal from the decision of Galen to observation of nature than a crowd of anatomists were ready to follow his method. He died in 1564.
One who, at Padua, had been first his pupil, then his co-laborer,—namely, Columbus, born at Cremona in 1490,—succeeded him. Columbus criticised, in some respects, the statements of his eminent predecessor, which he could better do, since he is said to have dissected fourteen bodies every year, as well as to have practiced venesection. He came so near to discovering the mystery of the circulation that it is strange how he could have missed it. He even appreciated the systole and diastole of the heart and the connection thereof with dilatation and contraction of the arteries. He knew, also, that the pulmonary veins conducted arterial blood, and that the pericardium was a shut sac. He even appreciated the lesser circulation, since he described how the blood left the right side of the heart and passed into the lungs, and came back through the veins into the left ventricle; because of this discovery, and in spite of his utter failure to appreciate the greater circulation, he has been by some regarded as entitled to the credit which is universally given to Harvey. From his position as teacher in Padua Columbus was called to Pisa, and from Pisa to Rome, where he died in 1559.

Another of the great anatomists of this period, second only in fame to Vesalius, was Eustachius, born about the beginning of the sixteenth century. He became physician to the Duke of Urbino, and in Rome a city physician and professor of anatomy, continuing to teach in the latter city until overtaken by his final sickness. He was a defender of Galen rather than an opponent, and sought to shelter his reputation from the attacks of Vesalius. In his praise it must be said that, for his day, he was a great anatomist; his chief discoveries were in the domain of comparative anatomy. He brought to bear upon his work a knowledge of embryology which enabled him, for instance, to describe the kidneys and the teeth much more accurately than would otherwise have been possible; he noted, also the pathological changes in bodies dissected, and is brought daily to our minds as we think of the connecting channel between the pharynx and the middle ear, to which his name has been given.
He died in 1574.
