In "The Masque of the Red Death," what are the gothic elements present?

When we think of Gothic literature one of the first things
that comes to mind is setting. Eerie towers at night, spooky graveyards, haunted houses,
deserted mansions and so on. Then we have to inject an element of the supernatural -
strange sounds, unexplainable happenings, supposed ghosts. If you look at novels that
are considered "Gothic" such as Jane Eyre or Wuthering
Heights, these are all key ingredients.

So, when
we think about "The Masque of the Red Death," we need to investigate if we can detect
Gothic elements in the setting and if there are elements of the supernatural. Certainly,
the setting seems to be particularly bizarre, and it is worth thinking about how it
operates symbolically. However, the last, black room, seems particularly Gothic in its
presentation:

The seventh apartment was closely shrouded in
black velvet tapestries that hung all over the ceiling and down the walls, falling in
heavy folds upon a carpet of the same material and hue. But in this chamber only, the
colour of the windows failed to correspond with the decorations. The panes here were
scarlet - a deep blood
colour.

Add this to the light
from the brazier that produces an effect "ghastly in the extreme," and you have a clear
Gothic setting here. Note too the element of the supernatural, with the uninvited guest,
whose costume makes him resemble a "stiffened corpse" and who disappears when
challenged. An obvious example of Gothic supernatural.

So,
in this story you can analyse the setting and also the element of the supernatural that
is introduced through the uninvited guest to find examples of how this story is
considered Gothic.
