The church cantata, according to Du Cange, dates back to 1314; but subsequent writers have shown that the term prior to the seventeenth century was used indiscriminately and without reference to any well-defined style of vocal music, and that as applied to church compositions it meant the anthem such as we now have, although not as elaborate. The noblest examples of the sacred cantata are those by Sebastian Bach, three hundred and eighty in all, over a hundred of which have been published under the auspices of the Bach-Gesellschaft. They are written in from four to seven movements for four voices and full orchestra, usually opening with chorus and closing with a chorale, the intermediate movements being in the form of recitatives, arias, and duets. The text of these cantatas is either a literal transcription of the Gospel or of portions of it. In the latter case the Gospel of the Sunday for which the cantata was written is introduced entire in the body of the work as the nucleus around which the great composer grouped the remaining parts. For instance, the cantata for Sexagesima Sunday turns upon the parable of the sower, and this being the Gospel for the day is made its central point. In like manner the cantata for the fourteenth Sunday after Trinity has for its subject the story of the ten lepers, which is introduced in recitative form in the middle of the work. The astonishing industry of Bach is shown by the fact that for nearly five years he produced a new cantata for each Sunday, in addition to his numerous fugues, chorales, motets, magnificats, masses, sanctuses, glorias, and other church music. The artistic sincerity and true genius of the old master also reveal themselves in the skill with which he finished these works for the congregation of St. Thomas,--few of whom, it is to be feared, had any conception of their real merit,--and in the untiring regularity with which he produced them, unrewarded by the world's applause, and little dreaming that long years after he had passed away they would be brought to light again, be published to the world, and command its admiration and astonishment on account of their beauty and scholarship.[5] Before passing to the consideration of the cantata in its present form, the following abridged description of those written by Bach, taken from Bitter's Life of the composer, will be of interest:--
