Keats tried to write poetry very early. Most of his early works were imitations. In 1817, with the help of Shelley, he published his first collection of poems, "Poetry". The collection of poems received some good reviews, but also some extremely harsh and offensive reviews in an influential magazine of the time (Blackwood's magazine). Undeterred, Keats made copies of a new collection of poems, "Endymion," the following spring.
