Why is Euripides the most tragic of playwrights?
I think Euripides explored and exposed more of the inner lives of the characters than Sophocles or Aeschyllus. His writing can be given to rhetorical excess, but that seems to be in line with the characters themselves — and a very human trait, in that we can all get carried away by emotion and become very speechy. His characters are also more individual, being more psychologically dimensional and particular than his contemporaries. I think they also relate to each other more, rather than merely make speeches at each other — there is some of that, as well, for such was the nature of theatre at the time, but in the exchanges between characters, there is more of a sense of people talking. His writing also explored female characters more sympathetically and individually than the others. Just my opinions.
