Focusing on a single artwork, Frans Post’s painting called The Oxen Cart of 1638, this article explores what Édouard Glissant calls the emotional apartheid of the plantation system. It argues that the affective evasion of Post’s painting fosters anti-Black racism by denying the full humanity of captive peoples. The painting is read together with Caspar Barlaeus’s contemporary apologia for the leadership of Maurits of Nassau, who was the governor-general of Dutch Brazil and Post’s patron. Focusing on classical and Neostoic understandings of governance and enslavement, the article turns to Paul Alpers’s analysis of the pastoral mode as an art of evasion that justifies the exploitation of rural labourers. It concludes by taking up Saidiya Hartman’s concept of critical fabulation to consider the oppositional views and counter-narratives expressed in the music-making traditions of enslaved people.
