 Wagner 's disciple Theodor <unk> followed Schumann 's <unk> line in his 1850 review of Le prophète : ' To a good Christian [ it ] is at best contrived , exaggerated , unnatural and slick , and it is not possible that the practised propaganda of the Hebrew art @-@ taste can succeed using such means . ' <unk> 's phrase ' the Hebrew art @-@ taste ' was to be used by Richard Wagner to spark off his attack on Meyerbeer , ' Das <unk> in der <unk> ( Jewishness in Music ) . ' ( see below ) .
