Robinson Crusoe

• Inspired the idea of children creating their own world of survival and adventure away from adults, similar to Crusoe's self-reliance on his island.
• Adapted the Robinsonade tradition by replacing a deserted island with the English Lake District, where children explore, camp, sail, and manage their own "island" experiences.
• Retains themes of resourcefulness, independence, exploration, and practical skills, showing young characters solving problems using their own abilities.
• Ransome transformed Crusoe's solitary survival story into a childhood adventure focused on imagination, teamwork, and outdoor exploration.

• Adopts the castaway survival premise of Robinson Crusoe, with stranded protagonists learning to survive on a remote tropical island.
• Expands Defoe's focus on self-reliance by emphasizing cooperation, friendship, and teamwork among three boys instead of a lone survivor.
• Retains themes of resourcefulness, exploration, and perseverance in an unfamiliar natural environment.
• Is widely regarded as a Robinsonade—an adventure novel directly inspired by and continuing the literary tradition established by Robinson Crusoe.

Martel is writing inside the form Defoe invented and takes its conventions seriously enough to itemise them: the inventory of salvaged supplies, the daily log, the rationing of water, the improvised shelter, the slow acquisition of competence. The theological frame is Defoe's too, since Crusoe reads his survival as providence and Pi's whole book is an argument about which story about God you choose to believe. The graph already holds Max e os Felinos here, which is the specific source; this is the tradition it sits in.
