What does Cassius say happened to Caesar during the campaign in Spain?

While on campaign in Spain, Caesar had an epileptic seizure. During the seizure he shivered like other men, lost all color, and his otherwise brilliant eyes lost signs of life. That day he was like any other man.... and according to Cassius, the people now see him as a god. Cassius is alluding to Caesar's humanity, and the fact that not all is at it seems. Caesar can be defeated.
