While opera is habitually performed in a foreign language, or, if in English, by those who have not the art of making their words intelligible, there will always be a demand for books that tell the story more clearly than is to be found in the doggerel translations of the libretti, unless audiences return with one accord to the attitude of the amateurs of former days, who paid not the slightest attention to the plot of the piece, provided only that their favourite singers were taking part. Very often in that classic period the performers themselves knew nothing and cared less about the dramatic meaning of the works in which they appeared, and a venerable anecdote is current concerning a certain supper party, the guests at which had all identified themselves with one or other of the principal parts in 'Il Trovatore'. A question being asked as to the plot of the then popular piece, it was found that not one of the company had the vaguest notion what it was all about. The old lady who, during the church scene in 'Faust', asked her grand-daughter, in a spirit of humble inquiry, what the relationship was between the two persons on the stage, is no figment of a diseased imagination; the thing actually happened not long ago, and one is left to wonder what impression the preceding scenes had made upon the hearer. Of books that profess to tell the stories of the most popular operas there is no lack, but, as a rule, the plots are related in a 'bald and unconvincing' style, that leaves much to be desired, and sometimes in a confused way that necessitates a visit to the opera itself in order to clear up the explanation. There are useful dictionaries, too, notably the excellent 'Opern-Handbuch' of Dr Riemann, which gives the names and dates of production of every opera of any note; but the German scientist does not always condescend to the detailed narration of the stories, though he gives the sources from which they may have been derived. Mr Streatfeild has hit upon the happy idea of combining the mere story-telling part of his task with a survey of the history of opera from its beginning early in the seventeenth century to the present day. In the course of this historical narrative, the plots of all operas that made a great mark in the past, or that have any chance of being revived in the present, are related clearly and succinctly, and with a rare and delightful absence of prejudice. The author finds much to praise in every school; he is neither impatient of old opera nor intolerant of new developments which have yet to prove their value; and he makes us feel that he is not only an enthusiastic lover of opera as a whole, but a cultivated musician. The historical plan adopted, in contradistinction to the arrangement by which the operas are grouped under their titles in alphabetical order, involves perhaps a little extra trouble to the casual reader; but by the aid of the index, any opera concerning which
