Answer:
These stories represent the highest achievements in the literary genre of the gothic horror story. By gothic, one means that the author emphasizes the grotesque, the mysterious, the desolate, the horrible, the ghostly, and, ultimately, the abject fear that can be aroused in either the reader or in the viewer. Almost everyone is familiar with such characters as Dr. Frankenstein's monster and Count Dracula, two of today's pop culture horror characters who evolve from the gothic tradition, and it is probably not an exaggeration to say that most adults in the Western world have been exposed to some type of gothic tale or ghost story. We all know that a gothic story or a ghost story will often have a setting that will be in an old, decaying mansion far out in a desolate countryside; the castle will be filled with cobwebs, strange noises, bats, and an abundance of secret panels and corridors, down which persecuted virgins might be running and screaming in terror. This is standard fare; we have either read about such places or seen them in the movies or on TV. The haunted castle is a classic setting of the gothic story. The author uses every literary trick possible to give us eerie sensations or to make us jump if we hear an unexpected noise. The shadows seem menacing in these stories, there are trap doors to swallow us up, and the underground passages are smelly, slimy, and foul — all these effects are created for one reason: to give us a sense of the ghostly and the supernatural.
Both "Ligeia" and "The Fall of the House of Usher" utilize many of these aspects of the gothic and are considered by critics to be not just among Poe's best short stories, but also among the finest examples of the gothic genre in all of literature.
Not surprisingly, both stories have many qualities in common: (1) In addition to the gothic elements, there is also a sense of remoteness and a sense of indefiniteness — that is, we are never told where "The Fall of the House of Usher" takes place in terms of setting; it could be in Ireland, Virginia, Scotland, Germany, or even Transylvania. The story could, in fact, take place anywhere as long as the area is remote to the reader, removed from his everyday environment. Likewise, "Ligeia"is set in an old castle on the Rhine or else in an abbey in the "most remote part of England." In both stories also, the time (the century) is set somewhere in the indefinite past. Clearly, it is not in an old castle in the present era.
(2) One of the primary aims of both stories is to create the single effect of an eerie and ghostly atmosphere and to do so, both stories emphasize the physical aspects of the various structures — the deep caverns or vaults where the Lady Madeline is buried and the weird room where the Lady Rowena died among various types of black sarcophagi. (3) In both stories, a super-sensitive hero is presented, a man who could not function well in the "normal" world. Roderick Usher and the narrator of "Ligeia" share a super-sensitivity to the point of maladjustment — due to the narrator's opium addiction in "Ligeia," and due to an undefined illness in Roderick Usher. (4) Often in the gothic story, the characters seem to possess some sort of psychic communication; this usually occurs between a member of the living world and a "living" corpse. In both stories, we see this kind of communication between, first, Roderick Usher and his twin sister and, again, between the narrator and his beloved, Ligeia. (5) One of the stock elements of the gothic story concerns the possibility of returning to life after one is dead and, moreover, inhabiting one's own corpse. Poe uses this effect to its very best effect in these two stories; both of them climax with just such an incident: To this purpose Poe created the return of the entombed and living corpse of the Lady Madeleine, as well as the slow re-emergence into life by the enshrouded Lady Ligeia. (6) In addition to the above features of the gothic story, Poe also stressed another similar element; he placed a strong emphasis on the life of the mind after the death of the body. This is also true of the stories associated with the Dracula legends, where the focus is upon the continuation of the life of the mind after the body has become a living corpse. The central concern of the Lady Ligeia is the continuation of the mind after physical death; Poe's emphasis here additionally stresses that one does not yield oneself to death except through a weakness of the will. Both in the Lady Madeline and in the Lady Ligeia, there is a superhuman strength to live — even after death. Both women
