How does Philippa Gregory use imagery in The Boleyn Inheritance?

Imagery:

"I can hear the roar of the feasting court from the hall as we walk toward it, serving men with great jugs of wine and platters of meat marching in line to serve the hundreds of people who dine every day with the king. In the gallery above are the people who have come to watch, to see the great monster that is the inner court of the noblest people, a beast with a hundred mouths and a million schemes, and two hundred eyes watching the king as othe only source of all wealth, all power, and all favor."

"And then suddenly a bulky man I don't know, a stranger smelling of sweat and wine and horses, pushes in front of us, into the window bay where we are standing, pushes rudely by me, and says to the Lady Anne, 'I bring you greetings from the King of England,' and he kisses her, full on the mouth. At once I turn to shout for the guards. This is an old man of nearly fifty, a fat man, old enough to be her father. She thinks at once that he is some drunk fool who has managed to push his way into her chamber."
