What is an example of imagery in the novel, My Brother Michael?

Imagery:

“The village is perched on a precipitous hillside, and the houses are built in tiers, one up behind the other, the floor of one level with the roof of the next. The whole village looks as if it were just about to slide into the depths of the valley below.”

“I'm not a person whom the sight of olive oil repels, and I love Greek cooking. We had onion soup with grated cheese on top; then the souvlaka, which comes spiced with lemon and herbs, and flanked with chips and green beans in oil and a big dish of tomato salad. Then cheese, and halvas, which is a sort of loaf made of grated nuts and honey, and is delicious. And finally the wonderful grapes of Greece.”
