Piscine Molitor Patel’s preferred moniker is more than just a shortened version of his given name. Indeed, the word Pi carries a host of relevant associations. It is a letter in the Greek alphabet that also contains alpha and omega, terms used in the book to denote dominant and submissive creatures. Pi is also an irrational mathematical number, used to calculate distance in a circle. Often shortened to 3.14, pi has so many decimal places that the human mind can’t accurately comprehend it, just as, the book argues, some realities are too difficult or troubling to face. These associations establish the character Pi as more than just a realistic protagonist; he also is an allegorical figure with multiple layers of meaning.
In Life of Pi, the color orange symbolizes hope and survival. Just before the scene in which the Tsimtsum sinks, the narrator describes visiting the adult Pi at his home in Canada and meeting his family. Pi’s daughter, Usha, carries an orange cat. This moment assures the reader that the end of the story, if not happy, will not be a complete tragedy, since Pi is guaranteed to survive the catastrophe and father children of his own. The little orange cat recalls the big orange cat, Richard Parker, who helps Pi survive during his 227 days at sea. As the Tsimtsum sinks, Chinese crewmen give Pi a lifejacket with an orange whistle; on the boat, he finds an orange lifebuoy. The whistle, buoy, and tiger all help Pi survive, just as Orange Juice the orangutan provides a measure of emotional support that helps the boy maintain hope in the face of horrific tragedy.
