What do you know about the narrative techniques used by Hawthorne in The Scarlet Letter? Nathaniel Hawthorne's The Scarlet Letter

It is
interesting that the scarlet letter rests upon a floor in "The Custom
House--Introductory" and it again lies upon a floor in Hawthorne's final chapter of his
seminal novel.  From beginning to end, Hawthorne's use of symbolism in  is
his most intriguing literary technique.  From this use of symbol and its enigmatic meaning,
Hawthorne weaves a narrative of great depth and implications.

With the
ambiguity of meaning created by the scarlet letter that rests upon the exterior of 's clothing,
the interior of 's clothing, and the incarnation of the letter in their child , Hawthorne forces
the absolutes of Puritanism and sin and guilt into question as various interpretations
of Hester's letter emerge with the narrative along with the three appearances of the letter. 
Clearly, Hawthorne's technique of symbolism provides the capacity to convey impressions and
meanings that extend beyond mere narrative.
