Epic - a long narrative poem that tells of the heroic deeds of a legendary hero. This comes from the oral tradition of singing songs of the heroic deeds of the knights and heroes of medieval times. A good example would be The Odyssey, a poem which recounts the deeds of Odysseus. The Illiad by Homer also recounts the deeds of the heroes of Troy.
Mock epic - a long narrative satire or parody of the epic form. They make fun of the heroes by either putting a fool into the role of the hero or exaggerating heroic qualities to the point that they are absurd. An example of this would be The Rape of the Lock by Alexander Pope.
Tragedy - a work of literature - usually a play -which results in a catastrophe for the main character. In ancient Greek times it was usually a king or heroic figure who had a flaw in his character that led to disaster. An example of this would be Oedipus in which the main character kills his father and marries his mother unbeknownst to him.
Novel - long work of prose either fictitious or partly so that tells a story. It has all the elements of a short story but, because of its length, can have one or more subplots or independent stories and a greater development of character. It may also have several themes. An example would be Great Expectations by Charles Dickens,
