This document discusses the literary elements of allegory and allusion. It defines allegory as a story that can be read symbolically to convey a deeper meaning. Allegory provides two meanings to a poem - a surface meaning and a symbolic meaning that conveys the true message. Allusion is defined as a reference to something assumed to be known, like historical events or other works of literature. The main function of allusion is to use references that readers will understand to portray complex concepts simply.
