The book studies metaphor myth and their imaginative aspects in the poetry of William Wordsworth Percy Bysshe Shelley and John Keats. Relying on Kantian Romantic NeoKantian and modern ideas of imagination metaphor and myth the book proposes that imagination is an inherently metaphorizing and mythologizing faculty because the act of perception is an act of giving form to natural phenomena and seeing similitude in dissimilitude which are basically metaphorical and mythological acts. Studying selected poems the author explores how in its formgiving activity the imagination of the speaking subject mythologizes and metaphorizes by seeing objects of nature as spiritual animate or divine beings and thus transforming them into the alien territory of myth.
