MAPA GENERAL DE ESPAÑA, construido por D. Tomás López, Geógrafo de los Dominios de S.M. 1770.
|DOCUMENT DESCRIPTION AND CARTOGRAPHICAL INFORMATION|
||GENERAL MAP OF SPAIN.|
|AUTHOR||Tomás Mauricio López de Vargas Machuca (1730-1802), known as Tomás López.|
|DATE OF EDITION||1770|
|PUBLISHER||Tomás López, who had founded a workshop to create and engrave his own maps after returning from France in 1760, also edits this map. He had been pensioned in Paris since 1752 together with other engravers sent by minister Marqués de la Ensenada
This is one of the first maps in which López included his honorary title of Geógrafo de los Dominios de su Majestad (his Majesty’s domains Geographer). He had just achieved it probably supported by Pedro Rodriguez de Campomanes, a rising politician and the director of the Real Academia de la Historia (Royal Academy of History) for which López worked since 1766 compiling cartography
|SUPPORTING AUTHORS||We don’t know the name of the other members of Tomás López workshop in this period. We only do between 1761 and 1763, when engraver Juan Antonio Salvador Carmona
|SCALE AND UNITS:||Four graphic scales are included: “twenty walk-hour leagues per degree”, “26 ½ legal Castilian leagues per degree”, “19 common Portuguese leagues per degree” and “25 common French leagues per degree”. The numerical scale, based on the document size and the graphic scales, is around 1:2.430.000.|
|REPRESENTED AREA||Iberian Peninsula and Balearic Islands, including parts of southern France and northern Africa.|
|SHEET DISTRIBUTION||The whole map is one sheet.
The secondary cartouche shows that the author had been editing particular maps of each province in a larger scale to “complete an Atlas of this Kingdom”. He started with Cordoba one in 1761, and that year he already published those corresponding to Jaen and Granada
|ORIGINAL DOCUMENT TYPE||Single ink paper chalcography. Some aquatint coloured boundaries. Bookbinding signs at the map midpoint. It’s one of the maps that the Real Academia de la Historia bookbinded in 1970 to form its Particular Atlas of Spain Kingdoms, Portugal and adjacent islands
|ORIGINAL SIZE||51 x 62 cm.|
|CARTOGRAPHIC ELEMENTS AND SYMBOLOGY||Small scale general map. It has the objective, as the cartouche reveals, of showing the province division at his time
The kingdom limits are represented by broken lines as well as the Capitanías Generales (“Captaincy Generals”), greater divisions that grouped several provinces belonging to the Crown of Castile: Old Castile, New Castile, León or Andalusia. They are coloured except those which, due to the chaotic jurisdiction of the old regime, were too complex to follow in a so small scale map, like New Castile (Castilla la Nueva) and Basque Country (Vascongadas). These major divisions are only named in the secondary cartouche.
Towns are labeled according to their magnitude, using italic and roman letters for smaller and greater ones respectively. Bishopric, archbishopric sees and the main monasteries are distinguished by symbols, while other entities are not easily recognized without a key-legend, which the map lacks.
Relief is displayed in a very simple way, by unlabelled side views of mountains serial drawing. However, the hydrographic network is better represented: the main rivers are thicker, some of them are labeled, and several lakes are included too.
Besides hydronyms, towns and province names, we can see toponyms like main capes, coastal features and some relevant divisions below the province rank like Asturias, la Montaña (Santander) and renowned regions like La Liébana, Sierra Morena, Montes de Toledo, los Pedroches or La Alpujarra.
|DATA COLLECTION PERIOD||From 1700 to 1770, approximately. See the “positioning methods and sources of information” section.|
|ORIGINAL PROJECTION SYSTEM||Due to the straight representation and specific structure of meridians and parallels we can infer they follow a polyhedric projection that doesn’t take earth curvature into account. It could be a trapezoidal projection, commonly used on regional scale maps between the XV and XVII centuries
|DATUM/SHAPE OF THE EARTH||The polyhedric projection converts the earth surface directly into a plane ignoring its curvature and without any kind of spherical shape for the planet.|
|GRATICULE AND GRID FRAME. PRIME MERIDIAN||One degree meridians and parallels grid. Ten minutes subdivisions frame. Latitude and longitude of origin at the Equator and the Meridiano de la Isla de Hierro (Ferro Meridian) respectively. This latter was situated in the western end of the known world at classic ages and was widely used since then, in part due to pre-modern French cartographers who traditionally placed this meridian at 20º west of Paris
The lower side of the map frame is referenced to Meridiano del Pico de Tenerife (Tenerife Meridian), located at 1º1’9,76’’ east of Ferro one
|POSITIONING METHODS AND SOURCES OF INFORMATION||Tomas Lopez developed his cartography by gathering information

Preliminary comment and evaluation
The obsolete maps from Tomás López ruled the Spanish cartographic scene during a large period between late XVIII and early XIX centuries. During that time, Cesar-Françoise Cassini was making the Map of France with accurate geodetic procedures and geometric surveys, which Spanish navy officers and other scientific-based cartographers applied too. On the other hand, Tomás López produced traditional workshop cartography from former maps and historical documents as well as from written descriptions compiled from local people, without any fieldwork, geodetic support or accurate considerations about earth curvature.
Tomás López was much better an engraver and cartography publisher than a map maker. Throughout most of the XVIII century, the art of engraving in Spain was far behind other European countries. In 1746 Antonio de Ulloa, working on the findings from the Meridional America journey he had undertaken (with Jorge Juan) to measure the terrestrial meridian, regretted the lack of reliable engravers that could produce the plates and expressed his preference for taking his work to France. In the end, these engravings were created in Madrid by Juan Bernabé Palomino, who was the King’s chamber engraver, requiring more time and money, just as Ulloa had feared. In 1756, following Enlightenment thought, Marqués de la Ensenada founded the Real Academia de Bellas Artes de San Fernando. Several engraving teachers guided by Palomino himself were enrolled. At the same time, four pensioned were sent to Paris in order to be instructed in engraving techniques: Manuel Salvador Carmona for “History and portrait engraving”; Alfonso Cruzado for “seals on fine stone”, and Juan de la Cruz and Tomás López, for “architecture, ornaments and geographic maps”. They learnt map engraving from ""Geographe du Roi" Jean-Baptiste Bourguignon d’Anville (1697-1782), cartographer specialized in map production from literary and historical information, and traveler’s stories. When López returned to Madrid in 1760, he founded the first engraving and editing map workshop in Spain and became the main cartographic reference thanks to his large production and the absence of competition.
Years later, in 1789, the current Secretary of State “Count of Floridablanca”, in his introduction on the first Gazetteer of Spanish towns, despised the already huge López work, referring to Lopez inaccurate way of working: “Nothing is more needed than a brand new general geographic map from the inner Peninsula (not based on particular descriptions or unlinked individual province maps) made by well instructed people, who, after visiting, watching and studying the field, will later use this information following the Cosmography, Geography and Chorography canons.” On the other hand, Floridablanca wrote two full pages praising the “so exact hydrographic Atlas” that Vicente Tofiño developed for the coastline using geometrical and geodetic procedures from new cartography.
In this maritime Atlas elaboration, supported by the government between 1783 and 1789, Lopez was not involved in chart engraving tasks, performed by his former Paris colleagues Juan de la Cruz and Manuel Salvador Carmona. It is not known if it was because of López’s refusal, maybe too immerse in his own work, or due to navy officers’ little enthusiasm about the non scientific methods of this cartographer. When Floridablanca was dismissed and the far less enlightened Manuel Godoy replaced him, Tomás López recovered the official favour and, in 1795, is requested to create a Geographic Office for the Secretary of State, and to elaborate the Atlas of Spain that he already started by his own at 1761.
On one hand, López General Map represents the old cartography; the one to be replaced by the new cartographic methods, whose evolution can be appreciated in the later maps included in this viewer. On the other hand, it shows the province division of the old regime, which will change as the new liberal state dismantles the absolutist regime, and can also be followed throughout the cartography shown here.
