The adventures of Robinson Crusoe penetrated into common consciousness and became world known. Thousands of editions- it could be spoken of 20 editions in Slovakia and 90 in Czech republic. But immense popularity caused that the true Robinson Crusoe is nearly unknown. For some readers the whole initial part, in which Robinson was captured on his journeys to Spain, Portugal after his rescue from the island will be absolutely new. Going through different editions, we will find out that our hero has completely different experiences, the plot is running differently. We can read in numerous remakes and overworks of this book that Robinson Crusoe comes from York, in other book form Hamburg or even form Bremen. We could only wonder how many varieties of Robinson Crusoe exist. They differ not only in initial and final parts, but also in the time the hero spent on the island: 28 years, 2 months and 19 days; or 17 years and 11 months or 11 years etc. Except of the intimately known Friday we can find in some books also a man named Thursday. But how is it possible that there are so many varieties of his book? The explanation is very simple. The book simply paid tax to its popularity.
