In Chapter 9 of Lord of the Flies, why is Simons dead body being carried out to sea a type of glorification?

Your
question suggests that Golding's description, in this regard, placesin an exalted position, that
he is deemed greater than he really is. In a religious sense, this would mean that he is, in
some way, the moral superior of all others.

The description makes it clear
that Simon holds a special place, to such an extent that even nature responds differently and
makes his water bound burial especially significant. His death is an almost spiritual event in
contrast to 's later sudden and graphically brutal demise. Golding describes the event as
follows:

Along the shoreward edge of the shallows the
advancing clearness was full of strange, moonbeam-bodied creatures with fiery eyes. Here and
there a larger pebble clung to its own air and was covered with a coat of pearls. The tide
swelled in over the rain-pitted sand and smoothed everything with a layer of silver. Now it
touched the first of the stains that seeped from the broken body and the creatures made a moving
patch of light as they gathered at the edge. The water rose farther and dressed Simons coarse
hair with brightness. The line of his cheek silvered and the turn of his shoulder became
sculptured marble. The strange attendant creatures, with their fiery eyes and trailing vapors,
busied themselves round his head. The body lifted a fraction of an inch from the sand and a
bubble of air escaped from the mouth with a wet plop. Then it turned gently in the
water.

The descriptors in the paragraph all deliberately
convey an event which has a surreal and extraordinarily supernatural value. It indicates a
special event and its significance is emphasized by the use of phrases such as "coat of
pearls," "a layer of silver," "patch of light," "brightness,"
"cheek silvered," and "sculptured marble." The images all convey light in
the surrounding darkness, not only in a physical sense but also metaphorically, for the boys
have been enveloped by the blackness of their innate evil. It is as if the reader is witnessing
something holy and only realizes that the text describes an otherwise ordinary event on reading
that "a bubble of air escaped from the mouth with a wet plop."

Simon's exalted state is further emphasized in the final paragraph where the journey to
his final resting place is given special significance. His body is surrounded by a halo (caused
by "a fringe of inquisitive bright creatures") to signify his spiritual purity and his
innocence.

Simon's demise symbolizes the death of innocence. He has become
the sacrificial lamb, as it were, for Man's inherent brutality. His burial, therefore, is
significant, for it indicates the final incarceration of Man's innocence. This further implies
that there is no going back -- Man is doomed to forever suffer from the consequences of his
iniquity.
