Shakespeare''s Romans are intensely concerned with constancy. Geoffrey Miles traces the Stoic origins of this Roman principle of being always the same and explores the varying forms it takes in writers such as Cicero Seneca and Montaigne. Building on this genealogy of constancy Miles reads Shakespeare''s Roman plays as reworkings of three figures found in Plutarch: the constant Brutus the inconstant Antony and the obstinate Coriolanus. The tragedies of these characters act out the attractions flaws and self-contradictions of constancy and the tragicomic failure of the Roman hope thatwere man/ But constant he were perfect.
