Many unusual and different animals have been described, glamorized and romanticized down through history, but dragons would
probably come out on top as far as popularity and recognition go. In almost every culture around the world, dragons have made an
appearance in myths and legends.
Dragon images have been found on the Ishtar Gate of Babylon, on scrolls from China, in Egyptian hieroglyphs and Ethiopian sketches,
on the prows of Viking ships, in bas relief on Aztec temples, and on cliffs above the Mississippi River.

In fact, the book of Job says ‘Canst thou draw out leviathan with a hook.. his breath kindleth coals and a flame goeth out of his
mouth... .’ (Job 41:1-34). In the Old Testament, the term dragon is used once referring to the Pharaoh King of Egypt as a dragon,
and the other times referring to animals; for example, ‘ ... the young lion and the dragon shalt thou trample under foot’, ‘And I will
make Jerusalem heaps and a den of dragons ... ’ .

Out of Hebrew Biblical texts, we found Gilgamesh, hero of an ancient Babylonian epic, who killed a huge reptile-like creature named
Khumbaba, or God Marduk. who defeated dragon goddess Tiamat, who challenged the stability of cosmos.
 
In Persia, dragon histories were the main subject for many artists during centuries XIII and XIV.  The Iskandar painting killing the
Dragon, made towards 1330, is a majestic representation of this  mythical story.  Also,  is the main subject of  the Shahnameh or
"book of kings"  written by Firdowsi.
 
Dragons are rife in Greek mythology. Hercules killed Ladon, a dragon that guarded the golden apple tree of the goddess Hera, in order
to steal the apples. Jason and the Argonauts stole the Golden Fleece guarded by a dragon. Cadmus killed a dragon that was sacred to
Ares, the God of War, and sowed its teeth from which sprung armed men.
 
A dragon was the Standard (pennant) of Romans. Last Roman emperors, had a lilac-purple dragon as ceremonial standard called the
Drakonteion and flew comets with their form. The famous roman writer Pliny, author of the 37 volumes of “Historia Naturalis” tell
us about a dragon that was killed during the reign of Emperor Claudius.
 
In Egypt, the gigantic Dragon- serpent Apep, which lived below the surface of the river Nile, fought the sun god Re every night and
tried to stop his journey in the sky. However Ra defeated him every day, and  triumphant raised again in the sky allowing  the sun to
shine.

The early Britons provide the first European accounts of reptilian monsters, one of which killed and devoured King Morvidus of Wales,
c. 336 BC. Another monarch, King Peredur, however, managed to slay his monster at a place called Llyn Llion, in Wales.

The epic Anglo-Saxon poem Beowulf tells how Beowulf (c. AD 495-583) of Scandinavia killed a monster named Grendel, and its
supposed mother, as well as several sea-reptiles, but eventually lost his life at the age of 88 in the process of killing a flying reptile.
Other well-known stories involving medieval heroes and dragons include Siegfried of the ancient Teutons (possibly the same person as
Sigurd of Old Norse, who slew a monster named Fafnir), Tristan (or Tristram), King Arthur, and Sir Lancelot, of Britain, and perhaps
the most famous of all, St George who became the patron saint of England.
 
Also they are present in the celtic world. Prince named Froech, son of a princess descending from the Tuatha De Danan, had to face a
dragon that guarded a magical rowan tree which grew on an island in the center of a large lake. During his task, he kills the dragon,
but looses his own life too.
 
Scandinavian people decorated the prow of their ships with fearsome figureheads, such as dragons or serpents. "Here be Dragons"
was  the phrase they used to mark the end of the known world, the unexplored lands.
In their mythology, we found Nidhogg, the Midgard-serpent, the greatest enemy of the mighty god Thor. According to the legend, using
a chain baited with the head of an ox, the Norse God Thor hauled the Midgard serpent from the sea. The serpent took the bait, and a
furious battle took place with Thor and the serpent struggling to overcome each other, but eventually, the exhausted Nidhogg escaped
sliding back beneath the water. Many years later, Thor finally killed the serpent on the day of Ragnarok, a battle to end all battles.
However Thor himself also died on this day  for the poison which the serpent spit at him.
 
In medieval times, dragons were seen as loathsome beasts that embodied destruction and evil. They were also symbolic of greed, rage,
envy and apostasy (loss of religious faith). Throughout Middle Ages, people enjoyed telling scary stories about knights challenging
dragons to battle. The mighty dragon was a popular subject in the art and literature, and they were represented in heraldry, palaces
and churches.
One of the most popular legends is the one referring to Saint George. He becomes patron of crusaders and everything else that had to
do with knights, weapons and fights. He also came to be considered as patron to the Crown of Aragon (Aragon, Catalonia, Valencia
and Majorca) Portugal, Greece, Italy and England.
The most well-known episode from the saint's life is the one represented  the famous combat in which the saint measured his strength
against that of a dragon in order to rescue a young princess, eventually defeating the beast.

The dragon ensign was used by many armies. Under the later eastern Roman emperors, the purple-dragon ensign became the
ceremonial standard, called the drakonteion. In England, before the Norman Conquest in 1066, the dragon was chief among the
royal ensigns in war, having been instituted by Uther Pendragon, father of King Arthur. Other kings who used the dragon ensign were
Richard I, in 1191, when on crusade, and Henry III, in 1245, when he went to war against the Welsh.
 
Alchemists in Middle Age, gave dragons the name of Ouroboros, the serpent biting, devouring, eating its own tail which symbolises the
cyclic Nature of the Universe: creation out of destruction, Life out of Death. The ouroboros eats its own tail to sustain its life, in an
eternal cycle of renewal. It is also an emblem of immortality. Its endless representation with its tail in its mouth, and the constant
renewal of its skin and vigor, enliven the symbols of continued youth and eternity.

In Oriental cultures, dragons are seen in a far more positive light. Revered as a primal force of nature, they represent power, longevity
and prosperity. In China,  dragons appear as the national symbol and the badge of the royal family, and the dragon adorned the
Chinese flag until the founding of the Republic of China, in 1911. The symbol of the dragon is used by the emperor (anyone else who
used it was put to death). Chinese refer themselves as "descendants of the dragon".
Chinese dragons are strongly associated with water in popular belief. They are believed to be the rulers of moving bodies of water,
such as waterfalls, rivers, or seas and so dragons are divided into: The Celestial Dragon (Tien-lung) protects the the sky and palaces of
Gods, The Spiritual Dragon (Shen-Lung) controls the wind and the rain, The Earth Dragon (Ti-lung) controls rivers, and water on the
Earth and The Underworld Dragon (Fut's-Lung) guards precious metals and gems.
Hong Kong was considered to be a safe city because of the nine mountains surrounding the area. Each mountain represented a dragon.
 
In Indonesia Dragons are called Nagas, and it was believed that an ancestor of the Pallava dynasty, married to a naga.
