A swan passionately defends its nest from an approaching dog, a struggle that, over time, came to be seen as a political allegory. In later centuries, the white swan was symbolically linked to Johan de Witt, the Dutch statesman who was assassinated in 1672. The scene was interpreted as representing his determination to safeguard the country from external threats and internal turmoil. This interpretation gained prominence when the painting was acquired in 1800 as the very first work for the Nationale Kunstgalerij, the institution that would eventually evolve into the Rijksmuseum. The allegorical reading of the piece helped cement its importance in the national consciousness and history.
