Two armored knights await the arrival of a dragon in the darkness of the wasteland, which they must kill. They have never seen it, but describe it as a huge, monstrous, one-eyed creature that breathes fire and smoke. When the long-feared confrontation finally occurs, the story takes an unexpected turn. The story, originally titled "The Dragon," by the celebrated American writer Ray Bradbury, was published by Esquire magazine in 1955 and later reissued in the 1959 anthology "Medicine for Melancholy." This edition retells one of the most acclaimed stories by the author of "The Martian Chronicles" and "Fahrenheit 451," in which one of the most important themes of his work can already be glimpsed: speculation about time and the threat of the future. The dragon takes on a symbolic value of the distance between the thinking of two periods in human history: the Middle Ages and the 20th century. However, there is not just one dragon; Svetlin's mastery delights us with a display of representations of this mythological creature, in which both the terror and the fantasy of the story are materialized, the outcome of which leaves a door open to the reader's imagination.
