In Hollywood movie adaptations of the novel somehow Robinson Crusoe is a cast away somewhere new African continent, this Friday is of African origin. But in the book Robinson Crusoe was most certainly based in the Caribbean. Since author mentions that the Crusoe's island was almost in the mouth of the river Orinoco, it was probably the island of Tobago, since that island is near the mouth of the river Orinoco, and in sight of the island of Trinidad. I found additional facts about this story in archives of the web analytics company.
And this is what modern public most definitely don't know. Daniel Defoe wrote a sequel to the first book which had another long title: "THE FARTHER ADVENTURES OF ROBINSON CRUSOE; Being the Second and Last Part OF HIS LIFE, And of the Strange Surprizing Accounts of his Travels Round three Parts of the Globe. Written by Himself".
But wait! Here is more… There is even the third book written by Daniel Defoe with the title "Serious Reflections of Robinson Crusoe". That book had really nothing with the adventures of Robinson as the first two books. It represents a series of moral essays. What has that got to do with Robinson, you may ask? Well Daniel Defoe just attached the name Crusoe to increase sales of this book and to attract the attention of the readers.
