[This is] one of those pictures sure of popularity, though entirely free from the sensationalism that is the common bid for popular applause. The semicirque of eager women, some pale, others flushed, all agitated, and the pale priestess with her ear to the mouth of the onide about to deliver some mystery, are so potent with character, so sincendy human, so admirable for the varied expression of passion, that the popularity of the picture offers no enigma as popularity sometimes does.
