In William Shakespeare's The Tragedy of Julius Caesar, the reader encounters an array of characters who exhibit a variety of personality traits. While some characters are purely good, others are purely evil; a few are a mixture of the two, such as Brutus, who is conflicted and has to choose whether to remain true as Caesar's friend, or to give in to his desire for power. Calpurnia, Julius Caesar's loving wife, is good.
In Scene ii of Act II, Calpurnia attempts to order her husband to remain home all day, despite his arguments. Calpurnia tells her husband that she has become frightened not only by the meteors and comets they have witnesses streaking across the night sky, but also by the terrifying sights seen by the town's watchmen. Calpurnia considers them to be bad omens, despite the fact that she has never been a superstitious person.
...A lioness hath whelped in the streets,
And graves have yawned, and yielded up their dead;
Fierce fiery warriors fought upon the clouds
In ranks and squadrons and right form of war,
Which drizzled blood upon the Capitol;
The noise of battle hurtled in the air,
Horses did neigh and dying men did groan,
And ghosts did shriek and squeal about the street.
O Caesar, these things are beyond all use,
And I do fear them...
When beggars die, there are no comets seen;
The heavens themselves blaze forth the death of princes.
