The XXX was made by whom?
The Battle of Alexander at Issus
Five of the paintings in William IV's original set of eight -- including The Battle of Alexander at Issus -- later passed from the royal collection to the Alte Pinakothek art museum in Munich, Germany, where they remain; the other three are in the National Museum of Fine Arts in Stockholm, having been looted by the Swedish army in the Thirty Years War of 1618--1648.
