gnashing of teeth
In his pain and anger the Creature imitates the actions of Victor
Frankenstein twice noted in the first volume (Letter 4 and note; 1.7.9 and note) and again at the
beginning of the second (2.1.2
and note). The Creature
will again be portrayed as gnashing his teeth in the third volume
(3.3.4). The prototype for this
behaviour remains the Satan of Milton's Paradise Lost, VI.340.
