Symonds describes at some length "Saint Uliva" and the interludes of Cecchi's "Esaltazione della Croce." The latter belongs to 1589, but it is almost certain that the manner of presentation was traditional. That similar splendors might have been exhibited in the fifteenth century we shall see later. Symonds thus describes the introduction to the "Esaltazione." A skilful architect turned the field of San Giovanni into a theater, covered with a red tent. The rising of the curtain showed Jacob asleep with his head resting on rocks, while he wore a shirt of fine linen and cloth of silver stockings and had costly furs thrown over him. As he slept the heavens opened and seven angels appeared sitting on clouds and making "a most pleasant noise with horns, greater and less viols, lutes and organ.... The music of this and all the other interludes was the composition of Luca Bati, a man of this art most excellent." After this celestial music another part of the heavens opened and disclosed God the Father. A ladder was let down, and God leaning upon it "sang majestically to the sound of many instruments in a sonorous bass voice." The other interludes were also filled with scenic and musical effects. For instance one showed the ecstasy of David, dancing before the ark "to the sound of a large lute, a violin, a trombone, but more especially to his own harp." These references to the employment of many instruments in accompanying the voice or the dance make us wonder whether our historical stories of the birth and development of the orchestra are well grounded. But we shall have occasion to consider this matter more fully when we approach the study of the musical apparatus of the first lyric dramas. It may be noted, however, in passing that the Italian word "violino" was used as late as 1597 to designate the tenor viol. This instance of uncertainty in terminology warns us to be careful in accepting all things literally. Perhaps what is of greater significance is the fact that there seems to have been more uniformity of effort and style in the first secular drama, doubtless owing to its great superiority as a piece of literary art. That sacred plays were seldom written by men of literary rank and ability we have already noted. That they were long drawn out, cumbersome, disjointed and quite without dramatic design has also been indicated. Their real significance as forerunners of opera lies in their insistent employment of certain materials, such as verse, music and spectacular action, which afterwards became essential parts of the machinery of the lyric drama.
