The work was written upon a commission given by the Cecilien Verein of Frankfort in 1831; but it was not produced until May 22, 1836, on the occasion of the Lower Rhine Festival at Duesseldorf. The principal parts were sung by Madame Fischer-Achten, Mademoiselle Grabau, Herren Schmetzer and Wersing, the latter artist taking the part of Paul. The second performance was given at Liverpool, Oct. 3, 1836; and between the two performances Mendelssohn revised the work and cut out fourteen numbers. After a long and expressive overture for orchestra and organ, the first part opens with a strong and exultant chorus ("Lord! Thou alone art God"). It is massively constructed, and in its middle part runs into a restless, agitated theme ("The Heathen furiously rage"). It closes, however, in the same energetic and jubilant manner which characterizes its opening, and leads directly to a chorale ("To God on High"), set to a famous old German hymn-book tune, "Allein Gott in der Hoeh' sei Ehr," which is serenely beautiful in its clearly flowing harmony. The martyrdom of Stephen follows. The basses in vigorous recitative accuse him of blasphemy, and the people break out in an angry chorus ("Now this Man ceaseth not to utter blasphemous Words"). At its close Stephen sings a brief but beautiful solo ("Men, Brethren, and Fathers!"); and as the calm protest dies away, again the full chorus gives vent to a tumultuous shout of indignation ("Take him away"). A note of warning is heard in the fervent soprano solo, "Jerusalem, thou that killest the Prophets;" but it is of no avail. Again the chorus hurls its imprecations more furiously than before ("Stone him to death"). The tragedy occurs. A few bars of recitative for tenor, full of pathos, tell the sad story, and then follows another beautiful chorale of submission ("To Thee, O Lord, I yield my Spirit"). Saul's participation in the tragedy is barely touched upon. The lament for Stephen is followed by the chorus, "Happy and blest are they," which is beautifully melodious in character. Saul now appears, "breathing out threatenings and slaughter" against the apostles. His first aria ("Consume them all") is a bass solo which is fiery in its energy. It is followed by the lovely arioso for alto, "But the Lord is mindful of His own,"--fitting companion to the equally beautiful "O rest in the Lord" from "Elijah," and much resembling it in general style. Then occurs the conversion. The voice from heaven ("Saul, Saul, why persecutest thou Me?") is represented, as was often done in the passion-music, by the soprano choir, which gives it peculiar significance and makes it stand out in striking contrast with the rest of the work. A forcible orchestral interlude, worked up in a strong crescendo, leads to the vigorous chorus, "Rise up! arise!" in which the powerful orchestral climax adds great strength to the vocal part. It is a vigorously constructed chorus, and is followed by a chorale ("Sleepers, wake! a
