What is the theme of Spencer's Fairy Queen?

The main purpose of the work is to cultivate new noble who conforms to the new bourgeoisie. The ideological content of the whole poem is complicated, including humanist's love for life, neo-Platonism's mystery, and Puritan's ethics. Spencer deliberately sought work in art and actively explored the form of poetry, creating a "Spenser's Poetry Festival" suitable for long poems, which had an important influence on Marlowe, Byron, Shelley and other poets, so he was called "the poet's poet".
