The
person I admire the most is Leonardo da Vinci. He was born on 15th April 1452
in the town of Vinci, Italy. His full name was Leonardo di ser Piero da Vinci,
which means Leonardo, son of Piero from
Vinci. He was not only one of the greatest painters of all time, but he was
also an architect, sculptor, engineer, inventor, mathematician and musician.

Leonardo da Vinci was a very intelligent and
imaginative man. He created many different designs. Some of them were for a
bicycle, a helicopter, a parachute and even an aeroplane! He also liked to
study everything in nature. You can find some of his notebooks in museums
today. In them you can see drawings of plants and animals as well as detailed
sketches of the human body!

Leonardo
da Vinci paid a lot of attention to detail and his paintings are very
realistic. The Mona Lisa, for example, is one of his best known works of art.
It is a painting of a woman whose face often makes people wonder if she is
smiling or not.

I admire Leonardo da Vinci for his amazing
works of art and his great inventions. His artwork will last forever and people
around the world admire it even today.
