 Metaphors are closely related to similes; but as opposed to the later tradition, Aristotle does not define the metaphor as an abbreviated simile, but, the other way around, the simile as a metaphor. The simile differs from the metaphor in the form of expression: while in the metaphor something is identified or substituted, the simile compares two things with each other, using words as “like,” “as”, etc. For example, “He rushed as a lion” is, according to Aristotle, a simile, but “The lion rushed” is a metaphor.
