The Viking experience throughout the north Atlantic was mainly about settlement with Iceland quickly becoming its most important colony . It is believed Iceland was colonised circa 870–930.  The Vikings explored the northern islands and coasts of the North Atlantic, ventured south to North Africa and east to Russia, Constantinople, and the Middle East.    They raided and pillaged, but also engaged in trade, settled wide-ranging colonies, and acted as mercenaries.  Initially, early Vikings would have returned home after their raids. It was not until later in their history that they began to settle in other lands.  Vikings under Leif Ericson , heir to Erik the Red , reached North America and set up short-lived settlements in present-day L'Anse aux Meadows , Newfoundland, Canada. This expansion occurred during the Medieval Warm Period . 
The music for the film was composed by Barry De Vorzon and Perry Botkin, Jr. Their score for the movie included an instrumental selection titled "Cotton's Dream," which was later rescored to become the theme song of the soap opera The Young and the Restless ; this was produced by Columbia's television division, now Sony Pictures Television . The soundtrack for the film also includes the movie's theme song , performed by The Carpenters . When gymnast Nadia Comaneci used the original music for "Cotton's Dream" for her routines in the 1976 Summer Olympics , the song gained more popularity and was subsequently released in a reedited and lengthened form as " Nadia's Theme ," under which title it became best known. (De Vorzon and Botkin Jr. also wrote lyrics for "Cotton's Dream," but no vocal version of it was known to have charted as of the last days of August of 2017.)
From the above arguments, explanations, and examples, we can easily infer the function of metaphors; both in our daily lives and in a piece of literature. Using appropriate metaphors appeals directly to the senses of listeners or readers, sharpening their imaginations to comprehend what is being communicated to them. Moreover, it gives a life-like quality to our conversations, and to the characters of the fiction or poetry. Metaphors are also ways of thinking, offering the listeners and the readers fresh ways of examining ideas and viewing the world.
