In _Lamia_ and _Hyperion_, as in _Endymion_, we find Keats inspired by classic story, though the inspiration in each case came to him through Elizabethan writers. Here, on the other hand, mediaeval legend is his inspiration; the 'faery broods' have driven 'nymph and satyr from the prosperous woods'. Akin to the Greeks as he was in spirit, in his instinctive personification of the lovely manifestations of nature, his style and method were really more naturally suited to the portrayal of mediaeval scenes, where he found the richness and warmth of colour in which his soul delighted. The story of _Isabella_ he took from Boccaccio, an Italian writer of the fourteenth century, whose _Decameron_, a collection of one hundred stories, has been a store-house of plots for English writers. By Boccaccio the tale is very shortly and simply told, being evidently interesting to him mainly for its plot. Keats was attracted to it not so much by the action as by the passion involved, so that his enlargement of it means little elaboration of incident, but very much more dwelling on the psychological aspect. That is to say, he does not care so much what happens, as what the personages of the poem think and feel. Thus we see that the main incident of the story, the murder of Lorenzo, is passed over in a line--'Thus was Lorenzo slain and buried in,' the next line, 'There, in that forest, did his great love cease,' bringing us back at once from the physical reality of the murder to the thought of his love, which is to Keats the central fact of the story. In the delineation of Isabella, her first tender passion of love, her agony of apprehension giving way to dull despair, her sudden wakening to a brief period of frenzied action, described in stanzas of incomparable dramatic force, and the 'peace' which followed when she Forgot the stars, the moon, the sun, And she forgot the blue above the trees, And she forgot the dells where waters run, And she forgot the chilly autumn breeze; She had no knowledge when the day was done, And the new morn she saw not-- culminating in the piteous death 'too lone and incomplete'--in the delineation of all this Keats shows supreme power and insight. In the conception, too, of the tragic loneliness of Lorenzo's ghost we feel that nothing could be changed, added, or taken away. Not quite equally happy are the descriptions of the cruel brothers, and of Lorenzo as the young lover. There is a tendency to exaggerate both their inhumanity and his gentleness, for purposes of contrast, which weakens where it would give strength. _The Eve of St. Agnes_, founded on a popular mediaeval legend, not being a tragedy like _Isabella_, cannot be expected to rival it in depth and intensity; but in every other poetic quality it equals, where it does not surpass, the former poem.
