![]() Petty had these measurements plotted, or “surveyed downe”(hence the name of the survey), onto manuscriptparish maps. The field surveyors used well-tried traversing methods where lengths were measured by chain, and bearings by a surveying instrument called a circumferentor. With the backing of a military government under Oliver Cromwell, he engaged a thousand men on the survey and completed the bulk of the work over a thirteen-month period in 1655-56. Rather, the success of Petty’s cartography was due to his organizing ability and his access to central government control. The scientific approach, which stresses the value-free, objective nature of maps, needs to be balanced with the idea that maps are also the products of other factors, including social, economic and political influences prevailing at the time the maps were made.įrom a scientific perspective, the Down Survey and atlas were not noted for cutting-edge methods. There is a growing acceptance amongst cartographic historians that an understanding of early maps is best achieved by integrating scientific and non-scientific approaches to map history. The effect of this ‘plantation’was dramatic: in the twenty-year period between 16, Catholic ownership of Irish land dropped from 60 percent to less than 10 percent. Its main source was Petty’s Down Survey, which was an instrument of state control designed to transform Irish society through a massive change in land ownership, from Catholic to Protestant hands. It became the definitive shape of Ireland for the next century.īut the atlas was more than a mirror of the physical and human geography of Ireland it was also testimony to the role maps themselves can play in the historical process. The general map provided the earliest, widely available outline of Ireland substantially as it is known today. The regional maps contained a level of accuracy and detail never previously printed and drawn to scale across a whole country. It was the first printed atlas of Ireland and the first in Europe to be based on measured surveys. Published under the title Hiberniae Delineatio in1685, it comprised a general map, a map of each of the four provinces, and thirty-two county maps.
