Falcon: The proud bird is a symbol
of Katherine. After Petruchio marries her, he has to figure out a way to make her into the wife
that he wants. To do this, he trains her like he would train a falcon. He denies her food
and sleep until she is willing to do anything that he wishes. He also shows her prizes such as
clothing and food which she desires, and then takes them away. She, like the bird, comes to depend on
him for these things and realizes it is her duty to love and serve him.
Christopher Sly: Like Baptista Minola, Christopher Sly believes anything that the Lords tell
him. He readily takes in the tutors and accepts their identities. He also accepts Tranio
as Lucentio without any sort of questioning.
The Sun and the Moon: The last real battle that Petruchio and Katherine has is about what is
lighting the sky, the sun or the moon. It is the middle of the day, so Katherine says it's the
sun. Petruchio on the other hand tells her it is the moon. The moon tells that Katherine
is still in "the dark" or "nighttime" about her behaviors and duties as a wife. When she finally
agrees with him, Petruchio says that it is the sun after all, symbolizing the fact that she has realized
her duties as a wife.
