Prague was late to the Mozart party, compared to Moravia. Smallpox or chickenpox broke out in Vienna in 1786, when Mozart was 11. The Mozart family went to Olomouc, first staying at the inn U Černého orla (At the Black Eagle), now known as Hauenschild Palace. Wolfgang, though, soon fell ill and was moved to the cathedral deanery. During his recovery, he composed Symphony No. 6 in F major. He was in Olomouc from October to late December 1767.
