 Lucas states that Seneca's writing, "tends to have less and less action, and the whole burden is thrown upon the language".The structure and style of Senecan tragedies such as "Phaedra" have exerted great influence on drama throughout the ages, particularly on tragedy in the time of Shakespeare.Technical devices such as asides and soliloquies, in addition to a focus on the supernatural and the destructive power of obsessive emotions, can all be traced back to Seneca.
