The contouring technique used by Robert Dawson on this map precedes the introduction of obligatory contouring on Ordnance Survey maps in 1839-40. Short watercolour lines ('hachures'), drawn with a brush, follow the direction of slope and are paced to indicate the steepness of relief. Colour washes are steadily built up, giving realism to the depiction of hills, mountains and, in particular, the thickly wooded valleys descending from the moors and downs towards the sea. Tin and copper mining is evident around Redruth and Camborne. A triangulation diagram is inscribed on the reverse of the manuscript but is now obscured by backing material.
A coloured chart of Falmouth Haven and the river Fal up to Truro; drawn 1590-1600
This sixteenth century drawing shows the layout of Falmouth harbour in Cornwall. It must have been drawn after the completion of Pendennis and St Mawes Castles in the 1540’s as these are depicted, although in a fanciful manner bearing little resemblance to the real structures. These castles were part of a defensive chain built by Henry VIII after a peace treaty was signed by Francis I of France and Charles V, Holy Roman Emperor and King of Spain in 1538, making invasion of England probable. England and France were ancient enemies and the catholic Charles V, nephew of Catherine of Aragon, was angered by Henry VIII’s decision to divorce her. Henry’s dissolution of the monasteries provided him with enormous wealth with which he was able to commission surveys of the vulnerable coastline and build defence fortifications.
This drawing was probably executed to provide a record of this vulnerable area of the coast for defensive purposes. It is possible that this drawing may date from 1598 – 1599 when the military engineer Paul Ivey was responsible for strengthening St Mawes and Pendennis following the 1597 scare that the Spanish might direct an armada towards Falmouth Haven.
Pictorial depiction’s of castles, ships and sea monsters feature on this map which verges on the fanciful in its details, the naval battle in the top left is simply an embellishment.
In the bottom left hand corner is a clover leaf pattern that is in fact an accurate ground plan of St Mawes Castle. A later annotator may have drawn this in an attempt to correct the picturesque inaccuracy of its depiction in this drawing.

Military batteries are marked along the coastline in this drawing. The profusion of defensive castles in this area is testimony to the perceived vulnerability of coastal regions. Red blocks indicate individual structures within the complex of Pendennis Castle, built by Henry VIII after his divorce from Catherine of Aragon aroused the hostility of Catholic France and Spain. The nearby castle of St Mawes acted as a seaward deterrent, protecting the anchorage of Falmouth. Half Moon Battery is indicated, as are signal seats along the extreme edge of the coast.
This drawing is attributed to Robert Dawson (1771-1860), a first-class Royal Military Draughtsman and Surveyor. He was also an influential teacher at the Tower of London Drawing Room, where he had been employed since the age of eighteen. The map is oriented unconventionally, with north to the left rather than at the top. Consequently, Lizard Head, the southernmost point of Great Britain, lies to the right of the plan. The boundaries of the area surveyed are coastal from Porthleven to Falmouth Bay, but at Lower Trenoweth they leave the coastline and follow the roads inland. The word 'flag' is written in several places (the tip of the Lizard, for example) to mark points between which Dawson took angular measurements to pinpoint topographical features. Similarly Signal Staff points are noted around the coast at Black Head and below Mullion Island. Helston was a tin-mining town. Copper and tin mines in the area are indicated by symbols.
South west coast of England from Exeter to Land's End, 1539-40
This is a map of the south-west coast of England, from Exeter to Land’s End. It dates from 1539-40 and its creation can be imputed to the threat of invasion which became probable in 1538 after a peace treaty was signed by Francis I of France and Charles V, Holy Roman Emperor and King of Spain. England and France were ancient enemies and the Catholic Charles V, nephew of Catherine of Aragon, was angered by Henry VIII’s decision to divorce her. Henry’s dissolution of the monasteries provided him with enormous wealth with which he was able to commission surveys of the vulnerable coastline and build defence fortifications. This map is the result of the order sent out by Thomas Cromwell in 1539 for the coasts to be surveyed by local people. These surveys, which were often just sketches or even text, were sent to London and in Greenwich they were edited, compiled and copied out for presentation to the King, who displayed them in Whitehall. The style of the map is pictorial with details such as ships, town views and fortifications shown in accurate detail. However, it contains vital practical information such as the state of defences and the distance between points along the coast and measurements at sea. Measurements at sea appear to be the estimated distance at which the navigator could discern features of the coastline. These are given in Dutch kennings probably due to the fact that the draftsmen in Greenwich included Flemish artists. The purpose of the map was to indicates, as if from the viewpoint of an invader, where landings could be made. Therefore, the cliffs, where landings would have been impossible are foreshortened, while the sandy beaches, where landings would have been easy are exaggerated in size. The sites for possible forts were then added to the map. The annotations on this map were made in about 1541 and record the state of fortifications, annotating made’ or not made’ over several fortification and half made’ over St Mawes Castle. Although this map contains measurements for use by sailors it is very unlikely that it would ever have been used at sea as it is almost 10 feet long and thus highly impractical for use within the confined space onboard ship.
PROMONTORIUM HOC IN MARE PROYECTUM CORNUBIA DICITUR Sheet 5
This map of Cornwall is from the 1583 edition of the Saxton atlas of England and Wales.This atlas was first published as a whole in 1579. It consists of 35 coloured maps depicting the counties of England and Wales. The atlas is of great significance to British cartography as it set a standard of cartographic representation in Britain and the maps remained the basis for English county mapping, with few exceptions, until after 1750. During the reign of Elizabeth I map use became more common, with many government matters referring to increasingly accurate maps with consistent scales and symbols, made possible by advances in surveying techniques. Illustrating the increasing used of maps in government matters, Lord Burghley, Elizabeth I’s Secretary of State, who had been determined to have England and Wales mapped in detail from the 1550s, selected the cartographer Christopher Saxton to produce a detailed and consistent survey of the country. The financier of the project was Thomas Seckford Master of Requests at the Court of Elizabeth I, whose arms appear, along with the royal crest, on each map.
PROMONTORIUM HOC IN MARE PROYECTUM CORNUBIA DICITUR f.8
This map of Cornwall is by Christopher Saxton. It forms part of an atlas that belonged to William Cecil Lord Burghley, Elizabeth I’s Secretary of State. Burghley used this atlas to illustrate domestic matters. This map is actually a proof copy of one which forms part of Christopher Saxton’s Atlas of England and Wales. This atlas was first published as a whole in 1579. It consists of 35 coloured maps depicting the counties of England and Wales. The atlas is of great significance to British cartography as it set a standard of cartographic representation in Britain and the maps remained the basis for English county mapping, with few exceptions, until after 1750. During the reign of Elizabeth I, map use became more common, with many government matters referring to increasingly accurate maps with consistent scales and symbols, made possible by advances in surveying techniques. This map was produced under the patronage of Thomas Seckford, a Master of Requests to Elizabeth I, who had commissioned Saxton’s atlas of county maps, a project overseen by Lord Burghley, Secretary of State, whose administration increasingly involved the use of maps. Here an annotation, probably by Lord Burghley, can be seen in the addition of a bridge at Truro. Such an addition is typical of Lord Burghley who was concerned with communication routes, such as roads and bridges, which were vital to the defence of the country, a central consideration during the reign of Elizabeth I, during which England was continually under threat.
