THE "Red Death" had long devastated the country. No pestilence had ever been so fatal, or so hideous. Blood was its Avatar and its seal --the redness and the horror of blood. There were sharp pains, and sudden dizziness, and then profuse bleeding at the pores, with dissolution. The scarlet stains upon the body and especially upon the face of the victim, were the pest ban which shut him out from the aid and from the sympathy of his fellow-men. And the whole seizure, progress and termination of the disease, were the incidents of half an hour.
Red, the color of blood and fire, is associated with meanings of love, passion, desire, heat, longing, lust, sensitivity, romance, joy, strength, leadership, courage, vigor, willpower, rage, anger, danger, malice, wrath, stress, action, vibrance, radiance, and determination.

Writers or speakers typically use allegories as literary devices or as rhetorical devices that convey hidden meanings through symbolic figures, actions, imagery, and/or events, which together create the moral, spiritual, or political meaning the author wishes to convey.
