Juan De La Cosa's Projection
Page 1 Coordinates Series A, no. 9 Juan de la Cosa’s Projection: A Fresh Analysis of the Earliest Preserved Map of the Americas Persistent URL for citation: http://purl.oclc.org/coordinates/a9.htm Luis A. Robles Macias Date of Publication: May 24, 2010 Luis A. Robles Macías ([email protected]) is employed as an engineer at Total, a major energy group. He is currently pursuing a Masters degree in Information and Knowledge Management at the Universitat Oberta de Catalunya. Abstract: Previous cartographic studies of the 1500 map by Juan de La Cosa have found substantial and difficult-to- explain errors in latitude, especially for the Antilles and the Caribbean coast. In this study, a mathematical methodology is applied to identify the underlying cartographic projection of the Atlantic region of the map, and to evaluate its latitudinal and longitudinal accuracy. The results obtained show that La Cosa’s latitudes are in fact reasonably accurate between the English Channel and the Congo River for the Old World, and also between Cuba and the Amazon River for the New World. Other important findings are that scale is mathematically consistent across the whole Atlantic basin, and that the line labeled cancro on the map does not represent the Tropic of Cancer, as usually assumed, but the ecliptic. The underlying projection found for La Cosa’s map has a simple geometric interpretation and is relatively easy to compute, but has not been described in detail until now. It may have emerged involuntarily as a consequence of the mapmaking methods used by the map’s author, but the historical context of the chart suggests that it was probably the result of a deliberate choice by the cartographer. -
Muslim Trade and City Growth Before the Nineteenth Century: Comparative Urbanization in Europe, the Middle East and Central Asia
British Journal of Political Science (2019), page 1 of 24 doi:10.1017/S0007123419000267 ARTICLE Muslim Trade and City Growth Before the Nineteenth Century: Comparative Urbanization in Europe, the Middle East and Central Asia Lisa Blaydes1* and Christopher Paik2 1Department of Political Science, Stanford University and 2Division of Social Science, New York University Abu Dhabi *Corresponding author. E-mail: [email protected] (Received 21 May 2018; revised 1 December 2018; accepted 9 May 2019) Abstract Scholars have long sought to understand when and why the Middle East fell behind Europe in its eco- nomic development. This article explores the importance of historical Muslim trade in explaining urban growth and decline in the run-up to the Industrial Revolution. The authors examine Eurasian urbanization patterns as a function of distance to Middle Eastern trade routes before and after 1500 CE – the turning point in European breakthroughs in seafaring, trade and exploration. The results suggest that proximity to historical Muslim trade routes was positively associated with urbanization in 1200 but not in 1800. These findings speak to why Middle Eastern and Central Asian cities – which had long benefited from their central location between Europe and Asia – declined as Europeans found alternative routes to the East and opened trade opportunities in the New World. Keywords: international trade; Middle East; Europe; Central Asia; urbanization; economic development The late fifteenth century is often heralded as a world historic juncture that ushered in the explor- ation, and eventual exploitation, of the New World; the Columbian Exchange of crops, peoples and diseases; and an age of colonial rule by Europeans. -

SETTING THE STAGE To the west of the Fertile Crescent in Africa, another river makes its way to the sea. While Sumerian civilization was on the rise, a sim- ilar process took place along the banks of this river, the Nile in Egypt. Yet the Egyptian civilization turned out to be very different from the collection of city-states in Mesopotamia. Early on, Egypt was united into a single kingdom, which allowed it to enjoy a high degree of unity, stability, and cultural continu- ity over a period of 3,000 years.

The question, however, remains as to what extent this reported scepticism truly reflects people’s opinions and feelings about Europe. We all consider it normal to cross borders within Europe, often while using the same money, as well as to take part in exchange programmes, invest in enterprises across Europe, and appeal to Europe institutions if national regulations, for example, do not meet our expectations. -
The Myth of the Square Chart
e-Perimetron , Vol. 2, No 2, Spring 2007 [66-79] www.e-perimetron.org | ISSN 1790-3769 Joaquim Alves Gaspar ∗ The Myth of the Square Chart Keywords : late medieval and renaissance nautical charts; cartometric analysis of maps; history of cartography; navigational methods of the discoveries period; map projections of old charts. Summary The first nautical charts used to navigate in the Atlantic, in the late Middle Ages and Renaissance, were identical to the portolan charts of the Mediterranean, only differ- ing in their geographic limits. With the introduction of astronomical navigation, and when a scale of latitudes was for the first time added to these charts, it quickly be- came obvious that their geometry had to be modified in accordance with the new navigational methods. The resulting hybrid model represented a major breakthrough in the nautical cartography of the Renaissance, marking the beginning of the evolu- tion form the “maps based on routes”, to the Ptolemy’s system of geographical co- ordinates. Using cartometric analysis, and taking into account the navigational methods used in the 16 th century, it will be shown that these charts were projection- less, in the sense that they were constructed plotting directly on the plane the ob- served latitudes, courses and distances, as if the Earth were flat. Introduction The genesis and evolution of nautical and terrestrial cartography in Europe are clearly distinct. When the first nautical charts appeared in the Mediterranean, probably during the 13 th century, no scientific cartography had yet been born. Contrasting with the practical purpose and accuracy of the portolan charts, the existing maps were symbolic representa- tions of an idealized world, strongly influenced by religion and mythology. -
Drought Condition and Management Strategies in Egypt
Egyptian Meteorological Authority 17-20 Oct 2014 Drought condition and management strategies in Egypt Author: Tamer A.Nada Supervisor: a Dr.Ahmed Abd Aal b Hamdy Abd El-Rahman aHead of the Central Department of Meteorology Research and Climate bDirector General of Climate in Egyptian Meteorological Authority Contents Background1 With the small exception of its strip of Mediterranean coastline and Narrow strip around the Nile River . The whole of Egypt has an arid desert climate. Throughout Egypt, days are commonly warm or hot, and nights are cool. Egypt has only two seasons: a mild winter from November to April and a hot summer from May to October. The only differences between the seasons are variations in daytime temperatures and changes in prevailing winds. In the coastal regions, temperatures range between an average minimum of 14 C in winter and an average maximum of 30 C in summer. Temperatures vary widely in the inland desert areas, especially in summer, when they may range from 7 C at night to 43 C during the day. During winter, temperatures in the desert fluctuate less dramatically, but they can be as low as 0 C at night and as high as 18 C during the day. The average annual temperature increases moving southward from the Delta to the Sudanese border, where temperatures are similar to those of the open deserts to the east and west. In the north, the cooler temperatures of Alexandria during the summer have made the city a popular resort. Throughout the Delta and the northern Nile Valley, there are occasional winter cold spells accompanied by light frost and even snow. -
Egypt's Nile-Red Sea Canals: Chronology, Location, Seasonality
J. COOPER: EGYPT’S NILE-RED SEA CANALS Egypt’s Nile-Red Sea Canals: Chronology, Location, Seasonality and Function John P. Cooper Introduction The Egyptian Nile was connected to the Red Sea by canal in a number of historical periods – the Persian (Achaeme- nid), Ptolemaic, Roman and Arab-Islamic. The creation of that connection was a major work of collective civil en- gineering and individual human effort. However, despite its scale, the canal remains very poorly understood. Little is known of the objectives of those commissioning it, the lives of those excavating and navigating it, its function and relationship to the wider world, or even its precise route through the Egyptian landscape. This paper draws upon historical, archaeological, carto- graphic, and remote sensing (satellite) data. It seeks to establish a chronology for the canal’s apparently episodic existence, to locate candidate routes for the canals of the various eras, and to assess its current archaeological state. It further uses historical and hydrological data to identify the canal as a seasonal waterway operating only during the Nile flood, and considers the implications of this season- ality for the canal’s role within Nile-Red Sea navigation. Finally, it investigates the possible objectives of the canal in the light of this seasonality, and of wider scholarship on the Red Sea. Summary maps of the areas discussed in this paper are provided for reference (Figures 20:1-20:2). Historical Data Accounts of a canal being contemplated, attempted or completed between the Nile and Red Sea appear in the historical record as early as Herodotus.
