The Faerie Queene, whose first three parts were published in 1590, and the second three in 1596, is considered Spenser's greatest work. By the 'Faerie Queene', Spenser signifies glory in the abstract and Queen Elizabeth in particular. Each of the six parts describes the adventures of one of the queen's knights, each knight exemplifying a different virtue; a fragment of a seventh intended part also survives. Ruskin characterized The Faerie Queene as 'true dreams; only the sleep of the men to whom they came was the deep, living sleep which god sends, with a sacredness in it as of death, the revealer of secrets', and included an analysis of the first part of the poem in an appendix to The Stones of Venice ( Works, 11.180).
