According to traditional practice, the spoils are carried along in the procession. They are called cultural treasures, and a historical materialist views them with cautious detachment. For without exception the cultural treasures he surveys have an origin which he cannot contemplate without horror. They owe their existence not only to the efforts of the great minds and talents who have created them, but also to the anonymous toil of their contemporaries.” -Walter Benjamin, On the Concept of History For my family.

Blakemore Faculty of History, University of Cambridge, UK This research note explores the possibility of approaching navigational instruments not as evidence of the progress of scientific knowledge, but of the experiences of early modern seafarers. These instruments formed an important part of the material culture of seafaring, existing as physical elements of the mental framework through which mariners understood both the natural and the human world around them. Some of these cultural contexts can be reconstructed through evidence such as navigational literature, ships’ journals, maritime court records, and seafarers’ wills.

  • Navigating with the Kamal M
    AstroEDU manuscript no. astroedu1647 c AstroEDU 2017 October 13, 2017 Navigating with the Kamal M. Nielbock Haus der Astronomie, Campus MPIA, Königstuhl 17, D-69117 Heidelberg, Germany e-mail: [email protected] Received July 14, 2016; accepted ABSTRACT The students build and use an old navigational tool from the Arab world of the 9th century, the kamal. After an introduction to historic seafaring and navigation, they build this simple tool and understand how it can be used to measure angles. After learning that the elevation of Polaris is (almost) identical to the latitude of the observer, they apply this knowledge while using the kamal. During a field trip, they actually measure the elevation of Polaris. The result is compared with modern methods. Key words.

  • Zheng He's Sailing to West Ocean
    International Journal Volume 1 on Marine Navigation Number 3 and Safety of Sea Transportation September 2007 An Important Waypoint on Passage of Navigation History: Zheng He’s Sailing to West Ocean J. Ding & Ch. Shi Shanghai Maritime University, Shanghai, China A. Weintrit Gdynia Maritime University, Gdynia, Poland ABSTRACT: Zheng He, a famous Chinese mariner, explorer, diplomat and fleet admiral of Ming Dynasty, sailed from China to many places throughout South Pacific, Indian Ocean, Bay of Bengal, Arabian Sea, Pesian Gulf, Red Sea and distant Africa in seven epical voyages from 1405 to 1433, some 80 years before Colubus’s voyages to America on Santa Maria. This magnificent feat in the history of navigation was later considered as a sheer waste of energy and money, and a “failure policy”. The scale of Zheng He’s navigation far exceeds that of Columbus’s “Great Discovery” which followed, but the former had less effect on the progress of the world history. In this paper, we recall Zheng He’s great adventure, as an important waypoint on the passage of navigation history. An introduction to the historical condition of that age and Zheng He’s family background is presented. The fleets, the passages, as well the experiences are illustrated. The shipbuilding technology and science of navigation of China in the ancient period are also demonstrated. And finally we discuss the historical significance, spirit and impact of Zheng He’s sailing. The great voyages are the magnificent landmarks not only in China’s political and diplomatic history but also in navigational annals of the world.

  • Words for Canoes: Continuity and Change in Oceanic Sailing Craft
    WORDS FOR CANOES: CONTINUITY AND CHANGE IN OCEANIC SAILING CRAFT ANNE DI PIAZZA Aix-Marseille Université Centre national de la recherche scientifique (CNRS) École des hautes études en sciences sociales (EHESS) Centre de recherche et de documentation sur l’Océanie (CREDO) Historically canoes are something of an enigma in the Pacific. They are extensively documented from the first contact period up to the present, but there is no widespread agreement pertaining to their design and technological innovations through time. Their few archaeological remains are not sufficiently informative, rendering such a topic challenging but, as developed below, historical linguistics can help to reconstruct Proto-Oceanic (POc), Proto-Central Pacific (PCP) and Proto-Polynesian (PPN) canoes. Pawley (2007: 26) has written: More than 20 terms for canoe parts and associated items are attributable to POc (Pawley and Pawley 1994). These include names for parts of a five-piece built-up hull, end pieces, projecting parts of the outrigger complex, platform, sail, boom of sail, steering oar, paddles, bailers, rollers for beaching and launching canoes, and anchors, indicating that POc speakers built substantial ocean-going outrigger canoes. Such lexical evidence supplements the paucity of archaeological data of pre-contact canoes but more importantly allows relative dating of technological innovations. By tracing the histories of cognates and/or semantic fields related to the canoe complex, we can learn a great deal about continuity and change in maritime history. This idea is not new. Geraghty (1994), Lynch (1994), Osmond (2003), Osmond et al. (2003), Pawley (2007) and Pawley and Pawley (1994) have used historical linguistics to reconstruct aspects of the canoe complex and the maritime environment.
