Power and Race in the Chesapeake In this 1670 painting by Gerard Soest, proprietor Lord Baltimore holds a map of Maryland, the colony he owned and which would soon belong to his grandson Cecil Calvert, shown in the painting as already grasping his magnificent inheritance. The presence of a young African servant foretells the importance of slave labor in the post-1700 economy of the Chesapeake colonies.
