Cassius Dio wrote that Pyrrhus "had a particularly high opinion of his powers because he was deemed by foreign nations a match for the Romans." He had for a long time coveted Sicily and considered how to overthrow Roman power, but he did not want to fight them "when no wrong had been done him." Both Cassius Dio and Plutarch wrote about Cineas, an important adviser of Pyrrhus. He was a man from Thessaly with a reputation for great wisdom who had been a pupil of Demosthenes the orator. Pyrrhus held him in high regard. Cineas saw the folly of an expedition to Italy. He tried to dissuade Pyrrhus and urged him to be satisfied with the possessions he already had, but Pyrrhus did not listen to him.
