Step-by-step explanation:
Horace is using metaphors to explain hypocrisy by using the names of well-known people and literary figures for comparisons. A metaphor compares two things by saying they are the same, without using the words 'like' or 'as'. By using these metaphors, Horace is able to illustrate the concept of hypocrisy by drawing parallels between well-known individuals and the behavior he is criticizing.
