In this lesson you will :
• explore the contributions of Greek
civilization.
• read a Greek myth.
• discover the first steps in the evolution
of human-powered flying machines.
• appreciate how a writer was fascinated
by flight.
Ancient Greek civilization was the
most influential the world has ever
known. Many aspects of it: its art,
its philosophy, its drama, its
educational system and its values
are prominent in our culture.
Some of the words we use today
are based on Greek civilization.
Take for example the phrase
“The Midas Touch”.
The Greeks were the first people in
ancient times who thought and acted
much like us. They were very curious
and thought about almost every
subject. They also had a strong
individualistic spirit, and would not
accept any law, rule or fact just
because somebody "said so."
Some of the Greeks' most
interesting ideas appeared in their
mythology, which usually mirrored
Greek society.
The myths' main purpose was to
explain the wonders of the world.
Let’s go to the
Webster Dictionary
to find a definition
for the word
“myth”.
The first man to fly, according
to Greek mythology, was the
skilled Athenian craftsman and
inventor Daedalus.
Daedalus was an architect and
inventor who designed the
Knossos labyrinth for Minos, the
cruel king of Crete. The Crete
civilization existed from the end
of the 3rd millennium BC.,
reaching its peak about 1600 BC.
3000bc____1600BC____AD- birth of Christ
BC means before the birth of Christ
AD means after date, Anno Domini
The labyrinth was built as a prison
for all the King’s enemies. They had
to face the Minotaur, a man-eating
monster that was half
man and half bull.
The labyrinth was so skillfully
designed that anyone who entered
could not find his way out. Thus, no
one could escape from the Minotaur.
Daedalus, however, revealed the
secret of the labyrinth to Ariadne,
Minos’s daughter, so that she could
help her lover Theseus kill the
Minotaur and escape.
Angered by the escape, Minos
imprisoned Daedalus and his son
Icarus in the labyrinth. Daedalus
made two pairs of wings out of
feathers, sticks and string so
that they could both fly out.
Icarus, however, flew too
close to the sun. His wings
melted and he fell into the sea.
Daedalus flew to Sicily,
where he was welcomed by
King Cocalus.

5) Daedalus
and his son were put in

escape. Y/N
6) Daedalus
made wings so that he
could fly out of the labyrinth. Y/N
Thousands of years after it
was first told, the story of
Daedalus and Icarus still
stirred the imaginations of
those who explored the
mysteries of flight.
Leonardo da Vinci (14521519), who lived about 2500
years after the ancient
Greeks, was also fascinated
with flight.
Leonardo da Vinci left over
500 sketches and 35,000
words in manuscripts devoted
to flying machines, bird flight
and the properties of air
flow. Yet, he had no influence
on the development of human
flight.
Which of the many of Da Vinci’s
inventions are connected with
flight?
These are examples
of his flight sketches.
Ironically enough Da Vinci had
no influence on the development
of human flight.
His life was filled with ironies.
While some people worked on
wings, others had taken to the
air in an entirely different way in balloons.
In the eighteenth century a
book on the properties of newly
discovered gases gave the
Frenchman Joseph Montgolfier
the idea that bags of gas might
rise in the air.
What gave Montgolfier the
idea that he could develop a
flying machine?
1. the discovery of new gases
2. the balloons he read about
3. a book about air
Hot – air balloons inspired
the imagination of
writers as well.
“Around the World in Eighty Days”
by Jules Vernes (1828-1905),
is a novel about the
adventures of Phileas Fogg
and his servant
Passepartout.
One day, while Phileas Fogg is
with some friends, he reads in a
newspaper that it is possible to
travel around the world in eighty
days and bets them that
he could make the journey
in that time.
One of the means of
transportation he and his
servant use on their journey
is a hot-air balloon.
Who traveled in a
hot-air balloon?
1. Jules Vernes and his
servant
2. Passerpartout and Fogg
3. Fogg and Vernes
Jules Vernes is a well known
author.Let’s find out some
details about his life and
write his biography.
The modern hot air balloon is
made up of three main parts:
the envelope,
the basket,
and the burner.
The envelope is the colorful “balloon”
part and is sewn into many patterns,
geometric designs and custom shapes.
The wicker basket (sometimes called
the “gondola”) is tightly woven so
that it will not get caught on tree
branches or entangled in power
lines.
When Jules Verne wrote this book,
he probably had no idea about how
much the world would advance.
Today, with the technology we
have, we can physically travel
around the world in about a day.
Man has wondered about the
possibility of flight for
thousands of years. Ancient
myths, songs, poetry and books
have been written to describe
the “flights of imagination.’’
In this lesson
you have gone through a timeline
from 3000BC to 1900AD,
discovering the world of flight in
people’s imaginations.
Daedalus built the maze
1. because the king asked him to.
2. to make it difficult for prisoners to escape.
3. both 1 and 2
Leonardo da Vinci
• had no influence on the development of
human flight.
• had a tremendous influence on the
development of human flight.
• had a partial influence on the
development of human flight.
