idk im sorry well i am new at this so im trying
The Roman poet Ovid, often is ranked as one of the three canonical poets of Latin literature.
The meaning of the phrase "art hides his art" is that he believed that the statue he has created is a piece of his art but what the statue holds for its self is also art, however, just because it does not have life the art it holds can not been seen.
This is an artistic expression, since they are able to portray their thoughts and feelings in a way that is everlasting. Hope this helps.
