What are some allusions (and explanations of allusions) from "The Cask of Amontillado" by Edgar Allan Poe?If you could list some and explain them...

ALLUSIONS IN EDGAR ALLAN POE'S "THE CASK OF
AMONTILLADO"

An allusion is a
literary figure of speech that makes a brief "reference to, or representation of, a
place, event, literary work, myth, or work of art, either directly or by implication."
The term is often mistaken for what is otherwise a "simple reference." There are several
examples of allusions in "TCOA."

• "He prided
  himself on his connoisseur-ship in wine. Few Italians have the true virtuoso spirit. For
  the most part their enthusiasm is adopted to suit the time and opportunity, to practise
  imposture upon the British and Austrian millionaires." -- The mention of the "British
  and Austrian millionaires" is an allusion to the subjects whom the Italian wine experts
  aim their verbal expertise.


• "It was about dusk, one
  evening during the supreme madness of the carnival season, that I encountered my
  friend." -- This alludes to the annual carnival (presumably in an unidentified Italian
  town), which occurs throughout many parts of the world.


• “
  'I forget your arms.' ”
  “ 'A huge human foot d'or, in a field azure; the foot
  crushes a serpent rampant whose fangs are imbedded in the heel.' ”
  “ 'And the
  motto?' ” '
  " 'Nemo me impune lacessit.' " -- Poe alludes
  here to both the Montressor coat-of-arms and the family
  motto.


• “ 'Then you are not of the brotherhood.'
  "
  “ 'How?' ”
  “ 'You are not of the masons.' ” -- An important
  allusion in the story, Fortunato is asking Montressor (by flashing a secret sign) if he
  is a member of the Freemasons, a secret brotherhood. Although Montressor claims that he
  is a member, he is not; instead, in an ironic twist, he holds up a trowel in response to
  the hand sign displayed by Fortunato. The trowel is a masonry tool--the one which will
  seal Fortunato's doom.
