* * *from Greekantitheton, “opposition”a figure of speech in which irreconcilable opposites or strongly contrasting ideas are placed in sharp juxtaposition and sustained tension, as in the saying “Art is long, and Time is fleeting.”The opposing clauses, phrases, or sentences are roughly equal in length and balanced in contiguous grammatical structures.The world will little note nor long rememberwhat we say here, but it can never forget whatthey did here.In poetry, the effect of antithesis is often one of tragic irony or reversal.Saddled and bridledAnd booted rade he;A plume in his helmet,A sword at his knee;But toom [empty] cam' his saddleA' bloody to see,O hame cam' his gude horseBut never cam' he!(“Bonnie George Campbell,” anonymous)
