The story takes place at the castellated abbey of the "happy and dauntless and sagacious" Prince Prospero. Prospero and one thousand other nobles have taken refuge in this walled abbey to escape the Red Death, a terrible plague with gruesome symptoms that has swept over the land.
Victims feel overcome by convulsive agony and sweat blood instead of water. The plague is said to kill within half an hour. Prospero and his court are presented as indifferent to the sufferings of the population at large, intending to await the end of the plague in luxury and safety behind the walls of their secure refuge, having welded the doors shut.
Summary of the story
One night, Prospero holds a masquerade ball to entertain his guests in seven colored rooms of the abbey. Six of the rooms are each decorated and illuminated in a specific color: Blue, purple, green, orange, white, and violet. The last room is decorated in black and is illuminated by a blood-red light: because of this chilling pair of colors, few guests are brave enough to venture into the seventh room. The room is also the location of a large ebony clock that ominously clangs at each hour, upon which everyone stops talking and the orchestra stops playing.
At the chiming of midnight, Prospero notices one figure in a dark, blood-splattered robe resembling a funeral shroud, with an extremely realistic mask resembling a stiffened corpse, and with the traits of the Red Death, which all at the ball have been desperate to escape. Gravely insulted, Prospero demands to know the identity of the mysterious guest so that they can hang him. When none dares to approach the figure, instead letting him pass through the seven chambers, the prince pursues him with a drawn dagger until he is cornered in the seventh room, the black room with the scarlet-tinted windows. When the figure turns to face him, the Prince falls dead. The enraged and terrified revelers surge into the black room and forcibly remove the mask and robe, only to find to their horror that there is no solid form underneath either.
Only now do they realize--too late that the figure is actually the Red Death itself, and all of the guests contract and succumb to the disease. The final line of the story sums up: "And Darkness and Decay and the Red Death held illimitable dominion over all."
Analysis
Like many of Poe's tales, "The Masque of the Red Death" has also been interpreted autobiographically. In this point of view, Prince Prospero is Poe as a wealthy young man, part of a distinguished family much like Poe's foster parents, the Allans. Under this interpretation, Poe is seeking refuge from the dangers of the outside world, and his portrayal of himself as the only person willing to confront the stranger is emblematic of Poe's rush towards inescapable dangers in his own life.
