picion by the clerical powers, who from time to time found 
means of discrediting him. The circumstances of his leaving 
Spain are not definitely known. One account has it that he 
made a_ post-mortem examination of a body which showed 
signs of life during the operation, and that he was required 
to undertake a pilgrimage to the Holy Land to clear his soul 
of sacrilege. Whether or not this was the reason is uncertain, 
but after nineteen years at the Spanish Court he left, in 1563, 
and journeyed to Jerusalem. On his return from Palestine 
he suffered shipwreck and died from the effects of exposure 
on Zanti, one of the Ionian Islands. It is also said that 
while on this pilgrimage he had been offered the position of 
professor of anatomy as successor to Fallopius, who had 
died in 1563, and that, had he lived, he would have come 
back honorably to his old post. 
Eustachius and Fallopius.—The work of two of his con- 
temporaries, Eustachius and Fallopius, requires notice. 
Cuvier says in his Histoire des Sciences Naturelles that those 
three men were the founders of modern anatomy. Vesalius 
was a greater man than either of the other two, and his 
influence was more far-reaching. He reformed the entire 
field of anatomy, while the names of Eustachius and Fallopius 
are connected especially with a smaller part of the field. 
Eustachius described the Eustachian tube of the ear and gave 
especial attention to sense organs; Fallopius made special 
investigations upon the viscera, and described the Fallopian 
tube. 
Fallopius was a suave, polite man, who became professor 
of anatomy at Padua; he opposed Vesalius, but his attacks 
were couched in respectful terms. 
Eustachius, the professor of anatomy at Rome, was of a 
different type, a harsh, violent man, who assailed Vesalius 
with virulence. He corrected some mistakes of Vesalius, 
and prepared new plates on anatomy, which, however, were
