60. But the most open and deadly hatred towards him was produced by his passion for the royal power. For the multitude this was a first cause of hatred, and for those who had long smothered their hate, a most specious pretext for it. And yet those who were advocating this honour for Caesar actually spread abroad among the people a report that from the Sibylline books it appeared that Parthia could be taken if the Romans went up against it with a king, but otherwise could not be assailed; [2] and as Caesar was coming down from Alba into the city they ventured to hail him as king. But at this the people were confounded, and Caesar, disturbed in mind, said that his name was not King, but Caesar, and seeing that his words produced an universal silence, he passed on with no very cheerful or contented looks. [3] Moreover, after sundry extravagant honours had been voted him in the senate, it chanced that he was sitting above the rostra, and as the praetors and consuls drew near, with the whole senate following them, he did not rise to receive them, but as if he were dealing with mere private persons, replied that his honours needed curtailment rather than enlargement. This vexed not only the senate, but also the people, who felt that in the persons of the senators the state was insulted, and in a terrible dejection they went away at once, all who were not obliged to remain, [4] so that Caesar too, when he was aware of his mistake, immediately turned to go home, and drawing back his toga from his neck, cried in loud tones to his friends that he was ready to offer his throat to any one who wished to kill him. But afterwards he made his disease an excuse for his behaviour, saying that the senses of those who are thus afflicted do not usually remain steady when they address a multitude standing, but are speedily shaken and whirled about, bringing on giddiness and insensibility. [5] However, what he said was not true; on the contrary, he was very desirous of rising to receive the senate; but one of his friends, as they say, or rather one of his flatterers, Cornelius Balbus, restrained him, saying: ‘Remember that thou art Caesar, and permit thyself to be courted as a superior.’
