What you can see is that each comparison follows a similar pattern:
- The monster introduces a point of comparison
- Describes that situation
- Then pivots to themselves
- And describes their own situation
By repeating this, Shelley creates a parallelism: two identical patterns which reinforce each other through their matching structures.
And if you were to look at the specific choices of comparison, you will notice they are two polar extremes: God and Satan.
We're not going to get bogged down in this level of detail in this lesson, but we wanted to highlight these patterns here in case you happen to find them useful as you're working on your own version.
