This distinction is often strongly marked in the practice of different artists. One poet may be both a pioneer of new roads in thought and a breaker of the laws of technique, like Walt Whitman--an enemy of the tradition in both kinds. Another may be slack and anarchical in his technique though quite conventional in his thought. I refrain from suggesting instances. Still more clearly there are poets, such as Shelley or Swinburne, whose works are full of intellectual rebellion while their technique is exquisite and elaborate. The thoughts are bold and strange. The form is the traditional form developed and made more exquisite. Now Euripides, except for some so-called licences in metre, belongs in my judgment markedly to the last class. In speculation he is a critic and a free lance; in artistic form he is intensely traditional. He seems to have loved the very stiffnesses of the form in which he worked. He developed its inherent powers in ways undreamed of, but he never broke the mould or strayed away into shapelessness or mere realism. His last, and in many respects his greatest, play, the _Bacchae_, is, as far as our evidence goes, the most formal that he ever wrote. These, then, are the lights in which we propose to look at Euripides. In attempting to reconstruct his life we must be conscious of two backgrounds against which he will be found standing, according as we regard him as Thinker or as pure Artist. We must first try to understand something of the tradition of thought in which he was reared, that is the general atmosphere of fifth century Athens, and watch how he expressed it and how he reacted against it. Next, we must understand what Greek tragedy was, what rituals and conventions held it firm, and what inner fire kept it living, and so study the method in which Euripides used it for his chosen mode of expression, obeying its laws and at the same time liberating its spirit.
