正确的诊断是（）| The history of Western music
properly begins with the music of the Christian, Church. But all through the
Middle Ages and even to the present time men have continually turned back to
Greece and Rome for instruction, for correction, and for inspiration in their
several fields of work; this has been true in music--though with some important
differences. R6man literature, for example, never ceased to exert influence in
the Middle Ages, and this influence became much greater in the fourteenth and
fifteenth centuries when more Roman works became known, at the same time, too,
the surviving literature of Greece was gradually recovered. But in
literature, as well as in some other fields (notably sculpture), medieval or
Renaissance artists had the advantage of being able to study and, if they so
desired, imitate the models of antiquity.
