文章的开头模彷了维吉尔的史诗埃涅阿斯纪。

The Faerie Queene is an incomplete English epic poem by Edmund Spenser. The first half was published in 1590 and a second installment in 1596. The Faerie Queene is notable for its form: it is one of the longest poems in the English language and the origin of a verse form that came to be known as Spenserian stanza. On a literal level, the poem follows several knights in an examination of several virtues, though it is primarily an allegorical work, and can be read on several levels of allegory, including as praise of Queen Elizabeth I. In Spenser's "Letter of the Authors" he states that the entire epic poem is "clowdily enwrapped in Allegoricall deuises," and that the aim of publishing The Faerie Queene was to "fashion a gentleman or noble person in vertuous and gentle discipline".
