Foucquet's most famous works in the Stockholm palace are the three central ceiling panels (1700–02) of the vault in the State Apartment of the north wing, the Gallery of Charles XI of Sweden. The paintings in this gallery and in the adjoining Cabinet of Peace and Cabinet of War depict a victorious king on the battle field during the Scanian War and the peace that followed when the Danish princess Ulrike Eleonora, sister of Christian V, married Charles XI. The iconography represent the King dressed as a classical military commander of Rome and the works are steeped in classical mythology.
