As a proof of the high favour in which he was held by the art-loving Charles VI., it is told that at the coronation of that emperor as king of Bohemia in 1723 an opera, La Constanza e la Fortezza, especially composed by Fux for the occasion, was given at Prague in an open-air theatre.

Fux died at Vienna on the 13th of February 1741. ”
