Percy Shelley is the purest brilliant in poetry. Reading his poems firstly - will be never forgotten! His lines do struck your heart enough with sincere and well charm, while feeding a words by words with your eyes, while tracing with a finger a letter by a letter...
Here's one of my favourite fragment from "Prometheus Unbounded".
"Head upon thy soul, by virtue of this Curse, Ill deeds, then be thou damned, beholding good; Both infinite as is the universe, And thou, and thy self-torturing solitude.
