Wolfgang fell ill, but he was well enough to perform before the Elector, with Nannerl, on 22 November. A few days later they set out for Salzburg, arriving at their home on the Getreidegasse on 29 November 1766. Evaluation Financial The party had survived major setbacks, including several prolonged illnesses which had curtailed their earning powers. Although Leopold did not reveal the full extent of the tour's earnings, or its expenses, the material benefits from the tour had evidently been considerable—but so had the costs. The librarian of St Peter's Abbey, Salzburg, thought that the gifts ("gewgaws") alone which they brought back were worth about 12,000 florins, but estimated the total costs of the enterprise at 20,000 florins. The expenses were certainly high; in a letter to Hagenauer sent in September 1763, after ten weeks on the road, Leopold reported expenses to date as 1,068 florins, an amount covered by their concert earnings without, however, any significant surplus. Leopold stated that "there was nothing to be saved, because we have to travel in noble or courtly style for the preservation of our health and the reputation of my court." He later recorded that on arrival in Paris in November 1763 that they had "very little money". At times, the coffers were full; in April 1764, near the end of the Paris sojourn and after two successful concerts, Leopold announced he would shortly be depositing 2,200 florins with his bankers. Two months later, after the initial London successes, Leopold banked a further 1,100 florins. However, in November of that year, after his illness and with uncertain earning prospects, he was worrying about the high costs of living in London—he informed Hagenauer that he had spent 1,870 florins in the four-month period since July. The following summer, after little concert activity, Leopold resorted to increasingly desperate measures to raise funds, including the children's daily circus performances at the Swan and Harp Inn at prices described by Jane Glover as humiliating. The insecurity of travelling life led Leopold to believe, later, that Wolfgang was not worldly-wise enough to attempt such journeys alone, and needed to be anchored to an assured salary. Musical In terms of musical development, while both children had advanced, Wolfgang's progress had been extraordinary, beyond all expectation. The Mozarts were now known throughout the musical establishments and royal courts of Northern Europe. As well as the encounters in palaces with
