James Cook was a famous English navigator, discov- erer and mapmaker. He was born in a small village in the north of England. At the age of seventeen he was sent to learn to sail on ships. He became very interest- ed in sea voyages and made a lot of them. He was at the head of the three expeditions round the world which made the knowledge about our planet deeper and wid- er. The maps he made were very good for those times. He discovered many islands in the Pacific Ocean and was killed on one of them by the native people.

Vasco da Gamma was born in Portugal. He was a fa- mous sea traveller and lived in the 15th century. He was the first to make a voyage from Europe to India which was very important for his country as it got new markets. The voyage was rather difficult and not very successful because the people in India were not very much interested in Portuguese goods and didn’t want to buy them. But the way to India by sea was discovered and that was a great success.

Francis Drake was born in 1540 in England. The Drake family was rather large. Francis’s parents had 12 children. Francis loved sea and left his native town fairly young. He got a ship as a gift from his friend, an old captain and made some far-away voyages. In 1577 Queen Elizabeth I sent Drake on an expedition against the Spanish ships. He took part in the war between En- gland and Spain in 1585 and destroyed the ships of the enemy. He died in 1596 at the age of 56 and was buried at sea. He was considered a hero by the English and just a pirate by the Spanish.
