Edgar Allan Poe pens an excellent short story mortifying, enlightening, disseminating a feeling of prudence, portraying Prospero, a prince, as he is assassinated, and as his closest court die, leaving disgust for the killer, and projecting courage to fight against such a foe: should Prospero have been strong and have lived incarcerating the villain that invades his party more may have lived.
For the masque worn by the killer in The Masque of the Red Death by Edgar Allan Poe covers the face of a criminal as is evidenced in the narrative and may cover the face of a marauder wanting to dethrone Prospero.
Courage to take action is important, and the calamitous consequences of nor doing so may be read in The Masque of the Red Death.
Also, this story brings to life the fatality of an infirmity that pervades a land seeming to leave no one alive.
So a complete feeling of foresight and the strength of will to act propel in Edgar Allan Poe's writing.
