Love. Its origin dates back to a time long past possibly before the discovery of fire in the dawn of the human species. A feeling that moves mountains, kibbles empires and changes the course of history is hard to define in just a few words.

Although only four letters spell it, love is a prism through which innumerable hues radiate, provoking powerful emotions that can lead to the ultimate sacrifice. We could also think of love as a movie with changing sceneries and costumes, rooted in different places and times, but whose eternal theme varies only with flourishes of fascination, commitment, devotion and renunciation.
 
Eternal tales
 
History is full of dramatic stories of legendary love affairs appearing in different cultures with the ever-present component of indescribable emotion. Curiously, these stories often begin quite suddenly and often through love at first sight.
 
From ancient Greece comes the story of Pyramus and Thisbe, who fell deeply in love, despite the opposition of their parents. When they make the decision to elope, a misunderstanding occurs and Pyramus believes that Thisbe was killed by a lioness. Upon learning this, Pyramus kills himself with his own dagger. When Thisbe realizes her lover is dead, she commits suicide. Thereupon they both undergo a metamorphosis. He becomes a river and she turns into a fountain. A number of more modern love stories draw inspiration from this tragic tale, including Romeo and Juliet by William Shakespeare, the Broadway musical West Side Story and The Fantasticks.
 
There is also an Aztec legend that goes back to the time before the arrival of the Spaniards. The legend states that an Aztec ruler had a beautiful daughter named Iztaccihuatl who was being groomed to become the empress. When she grew up, the princess fell in love with a young man named Popocatepetl who asked the emperor for her hand. The ruler agreed, but imposed a condition; the boy had to go to Oaxaca and bring back the head of an enemy chieftain as a war trophy.
