From Ludwigsburg they proceeded to Schwetzingen, and presenting recommendations from the Prince von Zweibrücken and Prince Clement of Bavaria, were well received by the Elector Palatine Karl Theodor. On July 18 the court assembled to hear them from five to nine o'clock; the children set all Schwetzingen in commotion, and the electoral household were enchanted with them. L. Mozart praises the admirable flute-playing of Wendling, and speaks of the orchestra as the best in Germany, being entirely composed of young men of good birth, who were "neither tipplers, nor gamblers, nor miserable ragamuffins" (a hit at Salzburg), and who were as estimable in their private as in their professional capacity. He goes on to inform pious Frau Hagenauer, that since they left Wasser-burg they had found no holy water, and rarely a crucifix in their bedrooms, and that they found it difficult to procure fast-day meals: "Everybody eats meat, and perhaps so have we, without knowing it. After all, it is no fault of ours!" Making an excursion to Heidelberg, Wolfgang played the organ in the Church of the Holy Spirit, and so astonished his audience that the Dean ordered his name and the particulars of his visit to be inscribed as a memorial of it on the organ. Unfortunately no trace of the inscription remains. At Mayence, owing to the illness of the Elector, Joseph Emnrerich (von Breidtbach), they could not appear at court, but made 200 florins at three concerts. Here they met the singer, Marianne de Amicis, who was returning with her family from London. At Frankfort, which they went out of their way to visit, Mozart's first concert, on August 18, was so successful that they decided on giving three more. The newspaper announcement, of August 30, 1763, shows what an astonishing performance was offered to the public. It runs as follows:[20017]-- {FRANKFORT, COBLENZ, COLOGNE.} (33) The universal admiration excited in the minds of the audience by the astounding genius of the two children of Herr L. Mozart, Kapellmeister at the Court of Salzburg, has necessitated the threefold repetition of the concert which was announced to take place on one occasion only. In consequence, therefore, of this universal admiration, and in deference to the desire of many distinguished connoisseurs, the next and positively the last concert will take place this evening, Tuesday, August 30, in the Scharfischen Saal, on the Liebfraoenberge.
