1699  GASCOYNE, Joel 

In Devon, Benjamin Donn in 1765 is acknowledged as the first to complete a map at 1” to the Mile to satisfy the requirements set the Encouragement of Arts, Manufactures and Commerce (later the Royal Society of Arts). However, it was actually Cornwall that can claim to have first been mapped at this scale – and 65 years earlier. Joel Gascoyne obtained commissions in Cornwall, surveying the estates at Kilkhampton of John Grenville and that at Lanhydrock for the Robarte family from c.1693 to 1699. Possibly taking advantage of the opportunity to travel and survey the county, he completed a map of the Duchy and announced it in a broadsheet 27th, March 1699. The following year he announced plans for a similar map of Devon, but these never came to fruition.[1]


Baptised in October 1650 in Kingston-Upon-Hull, Joel was apprenticed to John Thornton, where he learnt not only the skills of engraving but also surveying and chart-making; an unusual combination at the time. He started his career in London producing charts for John Seller and Thornton, and executed various maps as well as surveying lands in and around London. He worked in Cornwall until 1700 but died in Barking in 1705, when his wife, Elizabeth, was granted letters of administration.[2]

The map of Cornwall measures 1350 x 1795 mm and purports to have a scale of 1 In to the Mile. All the bridges over the Tamar are shown, but no roads continue into Devon. Although the 'Crimble paissage' is shown no road leads to it. Fully graticuled and with Latitude shown on both sides. An inset (Ab) shows the Isles of Scilly, and at the base of the map is a printed gazetteer. Roads are shown with double lines, solid or pecked.

There is a foliate frame beginning with the figure of Father Tamar (Tamer on map) cascading downwards to the beginning of the gazetteer. This forms a frame for the inset map of the Scilly Islands. A note within explains These Islands were not surveyed by the Author of the Mapp, but by Captain Greenville Collins whose skill and care is no ways questioned.
