The Footprint

Crusoe’s shocking discovery of a single footprint on the sand in Chapter XVIII is one of the most famous moments in the novel, and it symbolizes our hero’s conflicted feelings about human companionship. Crusoe has earlier confessed how much he misses companionship, yet the evidence of a man on his island sends him into a panic. Immediately he interprets the footprint negatively, as the print of the devil or of an aggressor. He never for a moment entertains hope that it could belong to an angel or another European who could rescue or befriend him. This instinctively negative and fearful attitude toward others makes us consider the possibility that Crusoe may not want to return to human society after all, and that the isolation he is experiencing may actually be his ideal state.

The Cross

Concerned that he will “lose [his] reckoning of time” in Chapter VII, Crusoe marks the passing of days “with [his] knife upon a large post, in capital letters, and making it into a great cross . . . set[s] it up on the shore where [he] first landed. . . .” The large size and capital letters show us how important this cross is to Crusoe as a timekeeping device and thus also as a way of relating himself to the larger social world where dates and calendars still matter. But the cross is also a symbol of his own new existence on the island, just as the Christian cross is a symbol of the Christian’s new life in Christ after baptism, an immersion in water like Crusoe’s shipwreck experience. Yet Crusoe’s large cross seems somewhat blasphemous in making no reference to Christ. Instead, it is a memorial to Crusoe himself, underscoring how completely he has become the center of his own life.

Crusoe’s Bower 

On a scouting tour around the island, Crusoe discovers a delightful valley in which he decides to build a country retreat or “bower” in Chapter XII. This bower contrasts sharply with Crusoe’s first residence, since it is built not for the practical purpose of shelter or storage, but simply for pleasure: “because I was so enamoured of the place.” Crusoe is no longer focused solely on survival, which by this point in the novel is more or less secure. Now, for the first time since his arrival, he thinks in terms of “pleasantness.” Thus, the bower symbolizes a radical improvement in Crusoe’s attitude toward his time on the island. Island life is no longer necessarily a disaster to suffer through, but may be an opportunity for enjoyment—just as, for the Presbyterian, life may be enjoyed only after hard work has been finished and repentance achieved.
