Chronicle for 1993

Abstract

Theory is not a goal in itself but a means of enriching the history of cartography by stimulating new research questions and objectives. In this paper the concept of ‘transparent maps’ (carriers of an image of the external reality of the world) and ‘opaque maps’ is introduced. The notion is approached structurally (standards of graphical representation, drawing, geometry, text); through the sociology of the map (map makers, institutions, the public); and through seeing maps in their cultural and historical context (an approach which raises issues of the definitional boundaries of the history of cartography and which is arguably one of the most stimulating perspectives today as fostered by, in particular, contributors to the History of Cartography). Finally, attention is drawn to three important topics for the research agenda: the links between maps and culture; maps as a language of communication and as instruments of power; and the links between perception, logic and mnemonics.     

The Railways of Britain: An Unstudied Map Corpus

ABSTRACT

Railway mapping, a distinctive genre of cartography, came into existence with the invention of railway transport in Britain. The planned route for the first public railway, the Stockton & Darlington Railway, was surveyed by 1820 as a statutory requirement for the Act of Parliament that was necessary before construction could proceed. The Stockton & Darlington Railway was granted its Act in 1821 and opened in 1825. From then on, an abundance of maps, plans, diagrams and technical drawings were created to enable railways to be planned, constructed and operated; to be changed, developed and regulated; to attract business and passengers; and to provide railway staff with a range of specialist tools. Today, Britain probably has the largest surviving corpus of such material, but owing to the essentially private nature of the preparation and use of railway maps, it remains largely unstudied and therefore scarcely evaluated in terms of its historical worth. This paper summarizes the archival history of Britain's railway maps and describes eleven broad categories of railway cartography that collectively form a coherent body of maps covering much of the nineteenth and twentieth centuries, and which await better access and comprehensive study. It also underlines the urgency of ensuring the preservation of the railway map archive from further loss and destruction.     

Cordiform Maps since the Sixteenth Century: The Legacy of Nineteenth‐Century Classificatory Systems

The heart‐shaped, or cordiform, maps of the sixteenth century, including those by Oronce Fine, Peter Apian and Gerard Mercator, have long intrigued historians. Most writers have considered the heart shape a product only of mathematics, but some have recently offered other interpretations for the use of the heart. A classificatory system devised by d'Avezac in 1863, however, has impeded our understanding of the cordiform map, particularly in the matter of what is considered to be such a map. The nature of his classification and its reception by other writers since the late nineteenth century are examined in order to elucidate new directions for the study of the use of the heart shape in sixteenth‐century cartography.     

Francisco Faleiro and Scientific Methodology at the Casa de la Contratación in the Sixteenth Century

Henricus Martellus's four world maps of c.1489 show a non‐existent Asian peninsula east of the Aurea Chersonesus (the Malay peninsula). For some decades a group of scholars in Latin America has been claiming that this so‐called ‘Dragon's Tail’ peninsula is really a pre‐Columbian map of South America. In this paper, the cartographical and place‐name evidence is examined, showing that the identification has not been proved, and that perceived similarities between the river and coastal outlines on this ‘Dragon's Tail’ peninsula and those of South America are fortuitous. Ptolemy's depiction of an enclosed Indian Ocean was invalidated when Bartolomeu Dias rounded the Cape of Good Hope. Consequently, a year or two later, Martellus adapted the east Asian section of Ptolemy's world map, providing China with an east coast and turning the southward extension of Asia into a peninsula. The non‐Ptolemaic place‐names on these maps were derived from Marco Polo's writings.     

Maps,Painting and Lies Portraying Napoleon's Battlefields in Northern Italy

A comparison of Giuseppe Bagetti's landscape sketches, watercolours, oil paintings and engravings with contemporary maps and the existing landscape reveals that in the creation of Bagetti's landscapes, narrative played a role that differed in cartographic and artistic representations. The comparison also demonstrates that his images were powerful constructions that were more successful in reflecting a narrative of glorious conquest than was possible through cartography. This paper offers a critical examination of Bagetti's representations of Napoleon's northern Italian campaign, which he sketched and painted between 1802 and 1809. Bagetti's paintings were neither pacifist nor an expression of Piedmontese patriotism but instead were inspired by, and constructed according to, a narrative about the conquest that reflected the views of the French authorities. The narrative found expression in formal written instructions from the central cartographical office in the Dépôt de la guerre, Paris, in verbal and written instructions from Bagetti's immediate superior, Jean François Martinel, and in letters personally addressed to Bagetti from the officer commanding the Dépôt. It is clear from a careful reading of the correspondence and from a comparison of Bagetti's paintings with both the present landscape and maps made at the time that Bagetti's disputes with his supervisors revolved around protecting his artistic integrity and reputation rather than resisting the authority of a foreign regime.     

两张英藏晚清广州洪兵舆图成图时间再考——兼及舆图成图时间考证的“断限逼近法”

成图时间考证是传统舆图研究中最初步最重要的工作,本文利用“断限逼近法”重新考察两幅清代广州洪兵舆图的成图时间。通过对新发掘档案的梳理,判断将F.O.931/1079图的成图前限推至咸丰四年六月二十四日的结论尚不成立,而F.O.931/1892图的成图断限则可由原来的八月三十日至九月初五日进一步推断为九月十一日至十二日。     

Feminist cartography and the United Nations Sustainable Development Goal on gender equality: Emotional responses to three thematic maps

Thematic maps facilitate spatial understanding of patterns and exceptions. Cognitive ability, spatial cognition, and emotional state are related, yet there is little research about map readers’ emotions. Feminist critiques of cartography recognize emotion and affect as legitimate experiences on par with quantitative ways of knowing. We conducted an online survey to measure users’ affective states before and after engaging with three thematic map types. The maps showed data from the United Nations Sustainable Development Goal to achieve gender equality, on the proportion of girls and women aged 15 to 49 who have undergone female genital mutilation/cutting. Participants viewed a choropleth, a cartogram, and a repeating icon tile map; completed map-related tasks; rated certain map qualities; rated their affective states before and after engaging with the maps; and answered open-ended questions. The maps piqued curiosity and evoked emotions for most users, while some users perceived the thematic maps as clinical or neutral despite the sensitive topic. After viewing the maps, female participants who were affected expressed deeper engagement in their open-ended comments than males. Traditionally, cartography construes the human experience as male experience and denies or trivializes women's experiences. Our findings corroborate feminist critiques of this disembodiment and entrenched rational rhetoric of maps.
