MAP of the Cape of GOOD HOPE & the Country adjacent
Map of Cape Colony in the mid Eighteenth century. Of note: triangulation for measuring the arc of the meridian at Cape Town. Map illustrates an article on Nicolas-Louis de Lacaille's survey to determine the shape of the earth at the Cape of Good Hope. Interestingly, despite flawless calculations and precise measurements, his results indicated that Earth was pear-shaped, an error caused by failure to take into account the Newtonian gravitational effect of the Cape mountains on the plumb bob.
Map of the Cape of Good Hope, Located on the Southern West Coast of Africa, Prime Meridian determined to be Paris. The map has one scale bar, represented in French Toise. There is a triangle on the map, not really sure what it depicts, a line of travel possibly.
