context: Early story. The discovery of the island by Europeans (about 1526-1542 year) XVII-XVIII century. Actually the "pirate period", when the island was used as a base, where you could stock up on fish, fresh water and wood for mending ships. According to legend, at this time the island becomes the famous "pirate safe." The end of the XVIII - the beginning of the XIX century. The least studied period. The island serves as a base for whalers, and is also used to replenish fresh water, firewood and ship timber. 1791-1932 years. The time of scientific description and study of the island. It begins with a visit to the island by naturalist Alejandro Malaspina and ends with the journey of Allan Hancock on the motor yacht Venero III. At this time, the island is being mapped, geologically surveyed, and island flora and fauna studied. 1879-1912: the colonial period. An attempt to turn the island into an exile prison, then - to establish an agricultural colony on it. Both attempts fail due to poor communication with the mainland and difficulties associated with human survival in tropical rainforests. The first quarter of the 19th century is today: treasure hunts and the era of tourism. About 300 large and small expeditions visited the island. None of them (at least officially) announced success. The last expedition led by John Hodges and Leonel Pacheco visited Cocos Island in 1992 and, like many others, left it empty-handed.
