inspiration of Life Of Pi

In a 2002 interview with PBS, Martel revealed his inspiration for his novel, "I was sort of looking for a story, not only with a small 's' but sort of with a capital 'S' – something that would direct my life." He spoke of being lonely and needing direction in his life. The novel became that direction and purpose for his life.
Martel also stated that his inspiration for the book's premise came from reading a book review of Brazilian author Moacyr Scliar's 1981 novella Max and the Cats, about a Jewish-German refugee who crossed the Atlantic Ocean while sharing his boat with a jaguar. Scliar said that he was perplexed that Martel "used the idea without consulting or even informing me," and indicated that he was reviewing the situation before deciding whether to take any action in response. After talking with Martel, Scliar elected not to pursue the matter. A dedication to Scliar "for the spark of life" appears in the author's note of Life of Pi.
Literary reviews have described the similarities between Life of Pi and Max and the Cats as superficial. Reviewer Peter Yan wrote, "Reading the two books side-by-side, one realizes how inadequate bald plot summaries are in conveying the unique imaginative impact of each book," and noted that Martel's distinctive narrative structure is not found in Scliar's novella. The themes of the books are also dissimilar, with Max and the Cats being an allegory for Nazism. In Life of Pi, 211 of 354 pages are devoted to Pi's experience in the lifeboat, compared to Max and the Cats, in which 17 of its 99 pages depict time spent in a lifeboat.
