Some think that dragons really existed in immemorial times, which then inspired the fantastic legend that therefore affirms their existence. Others think that they were a biological variant of some dinosaurs, although do not exist empirical evidence to support this thesis. The archaeologists and crypto zoologists affirm that giant lizards of characteristics similar to the ones attributed to the dragons existed, which they called “Megalania”. Nevertheless it did not turn out viable to affirm that they were the same type of animal.
Another less extended belief is that dragons were in fact one class of flying machines created by certain unknown archaic culture. This hypothesis, at the present time, is considered pseudo-scientist.
Formerly it turned out reasonable to maintain that the first found fossils of dinosaurs were, in fact, dragon bones. A discovery conducted by Chang Qu during the III century in Sichuan, China, catalogued the remains with that label.
Herodotus -called often the father of history- visited Judea in the year 450 A.C and listened to tales about the existence of encaged dragons in Arabia, near Petra, Jordan. This woke up his curiosity and decided to travel there. According to the testimonies written by this historian, he found two specimens of dragons with wings that had been locked up in an iron cage, it was characterized like true “ferocious beasts”. The Newspaper of Marco Polo explains that when he was walking by Anatolia, in Persia, he found dragons alive that could fly and that they attacked his caravan in the middle of the desert. In these chronicles, Marco Polo explained that they were frightful beasts that were on the verge of killing him.
Another hypothesis: the followers of the Catastrophism have suggested that comets and meteor rains were the astronomical phenomena that gave origin to the legend about fire serpents able to cross the firmament at great speed, and that’s how the belief in dragons was born.
A less credible affirmation indicates that the dragon was a compound creature. The idea rooted deeply in many cultures about the dragons, which suggest they have characteristics similar to three types of predators: they have legs, claws, capacity to crawl and a feline cleverness, for that reason they looked like leopards. By its capacity to fly and to have its lair in a far away place, generally rocky places like the eagles. But the dragons keep greater similarities with the serpents; in fact, our modern word “dragon” comes indirectly from the Greek, through Latin, in which drako means “serpent”.
In Greek myths there are many legends where these fabulous animals are mentioned; generally, the serpents or dragons guard treasures. For example, the hundred-headed dragon named Ladon, that guarded the gold apples of the Hesperides, daughters of Atlas, who kept the sky over his shoulders. Another dragon with serpent-like characteristics guarded the gold cloth of Aetes, king of Colchis, to protect it from been stolen by Jason and the Argonauts.
