In John Keats, "Ode on a Grecian Urn", a boy finds himself entangled in his dream about an ancient carving. Keats uses an assortment of techniques to bring life to the work and make it more enjoyable to read. Using these techniques helps keep the readers attention, while also helping the reader to better relate to the situation. Imagery is the technique most widely used, probably because everyone can relate to it in their own way. John Keats uses imagery to make the reader truly feel what he is describing. One of Keats' examples of imagery is found at the begining of the second stanza when he writes, "Heard melodies are sweet, but those unheard are sweeter."
