Ernest Hemingway used copious amounts of imagery in his World War I novel, A Farewell to Arms. In the five books that make up the novel, the mind witnesses the senses of sight, touch, smell, hearing and taste. All these senses in a certain sense connect to the themes that run through the novel. We can see Hemingway's writing style in greater depth and almost feel, or mentally see the First World War and the effects it generates through the eyes of Lieutenant Henry. In the first book of A Farewell to Arms, we read about the sense of taste. Taste plays an important role, as we appreciate the flavor of specific foods or liquids, sometimes even making us crave it. “It tasted like rusty metal, I handed the canteen back to Passani” (Page 54, Hemingway). The wine in which Lieutenant Fredric Henry's taste buds had been consumed was rotten. The reader could taste this “rusty metal,” almost reminding him of the taste of blood with its metal-like flavor. Hemingway shows us his writing style by giving us a distinct glimpse of how your body must crave some food or liquid to quench the hunger/thirst your body craves. Henry declared that the wine tasted like “rusty metal,” but continued to drink it a little later anyway. Perhaps the “rusty metal” flavor of the wine could represent blood, since blood tastes like metal, it could almost foreshadow that blood will soon be shed from the incoming bombardment. Wine also represents the theme of diversions, Henry continues to consume this rotten wine to divert his thoughts somewhere else. He would rather savor the rottenness of the wine instead of lingering with his thoughts on almost pungent thoughts of war and death. Touch is important in our lives, as we feel and touch things every day, our fingers perhaps grazing the rough surface of a rock or a piece of soft fabric. We can also mentally or physically experience feelings for protection. Henry describes Catherine Barkley's hair in the second book of the novel and how he feels so protected by it. “I would watch her as she stood very still and then I would take out the last two pins and it would all come down and she would put her head down and we would both be in it, and it was the feeling of being in a tent or behind a falls” (Page 114, Hemingway).
