I n 1778, a 25-year-old lieutenant named Peter Lotharius Oxholm arrived on the Caribbean island of St. Croix. He was tasked with surveying the Danish-Norwegian West Indies, as well as proposing the improvement of their fortifications. 1 The survey of the three islands proved so difficult and laborious, however, that Oxholm nearly gave up, noting that '[t]hese islands are nothing but mountains and cliffs, where it is almost impossible to survey or prepare a geographic large scale map before one has first cut lines and ways through the bush to get on'. 2 'One' here notably refers mostly to enslaved workers that accompanied Oxholm, six of whom were required for the survey of St Croix. Suggested is also the centrality of enslaved knowledge in the mapmaking process, as he further informs us that the enslaved used the 'necessary instruments' [triangulation] to complete the task. 3 Following the completion of the survey, Oxholm eventually drew a large-scale map of St Croix which was engraved and printed in 1799. This essay focuses on the accompanying figurative cartouche that identifies the map (figure 1). I argue that the cartouche is a material manifestation of the ideology of slavery as an opposition between black and white. Reading the cartouche and Oxholm's writing on sugar production against the grain, I also propose that it reveals an anxiety about the economic and social instability of slave society. The cartouche comprises a sign displaying the title 'St Croix', represented as a sheet hung over two hollowed poles jutting out from each side, suggesting a cross. The sign is positioned in a landscape firmly marked as a West Indian plantation society, both an imaginary and a 'real' site of labour. In front of the sign, on either side, are black figures. On the right is a seated woman holding two children. The woman's head is in profile and all look up in the same direction. To the right of this group is a small tent-like structure, within which are two low containers or mattresses, conceivably containing infants.
