Ferdinand III is portrayed here as victor over the Protestant forces in the Thirty Years War, the military context underlined by his armour and baton. On the table is an engraving or drawing of the Battle of Nördlingen in 1634, in which the imperial troops defeated the Swedish and Saxon forces. This and the style of the painting have led to the assumption that it dates from around 1638, when Luyckx was appointed at the court of Ferdinand III.
