This volume publishes for the first time, the journal kept by John Looker (?1670—1715) recording his service as ship’s surgeon on the Blackham Galley, a London-built merchantman on its second trading voyage to the Levant, between December 1696 and March 1698. Preserved in the Caird Library of the National Maritime Museum, Looker’s ‘Journall’ describes his experiences on the voyage from the point at which he joined the ship at Gravesend, to March 1698, when the journal breaks off abruptly in mid-sentence when the ship was off the Kentish ‘Narrows’. John Looker was a Londoner, brought up in one of the parishes to the east of the City which furnished large numbers of mariners to the English sea-borne trades. He served an apprenticeship to a London barber-surgeon, and became a Freeman of the Company of Barber-Surgeons. His fifteen months of service on board the Blackham Galley appears to have been his only employment at sea, but his ready knowledge of maritime ways and language, which are apparent from the first pages of his ‘Journall’, make it more than likely that he came from a seafaring family. Subsequent to his voyage, he married, raised a family, practiced in London as a surgeon, and acquired land in East Anglia. He died at Bath in 1715. Looker’s ‘Journall’ divides naturally into three parts. The Blackham Galley’s outward and homeward voyages were largely without incident. The time spent by the Blackham Galley in Turkish waters, covers its voyage from Smyrna to Constantinople, where the ship stayed for a month, and then returned to Smyrna. Captain Newnam’s ill-advised and disastrous attempt at privateering in Ottoman waters on the return journey to Smyrna, led to the detention of his vessel at Smyrna under a double interdict from the English ambassador at the Porte and from the Ottoman authorities. Looker’s account of the Blackham Galley’s enforced stay in Smyrna furnishes a vigorous and detailed account of social life in the international merchant community, as well as portside life seen ‘from below’, with its taverns and prostitutes, and the activities and frequent ‘debauches’ of an increasingly bored and fractious crew. Looker’s record also provides interesting detail of his professional approach to treatment of the illnesses, accidents and occasional deaths of members of the company of his own and other ships anchored off Smyrna.

Edmond Halley (1656-1742), MA, LLD, FRS, Capt. RN, Savillian Professor of Geometry and Astronomer Royal, stands pre-eminent among Oxford, English, and European scientists. A contemporary of Wren, Pepys, Hooke, Handel, Purcell, and Dryden, he was a schoolboy in London while the Great Fireraged, and was an active participant in the Enlightenment, an age of profound developments in all the arts and sciences. As a younger contemporary of Isaac Newton, he had a crucial part in the Newtonian revolution in the natural sciences. It was Halley who set the question that led Newton to writethe Principia, and who edited, paid for, and reviewed it. In later years he applied the methods of the Principia widely in astronomy and geophysics. Now more widely known for his prediction of the return of "his" comet, Halley discovered the proper motion of stars, made important studies of themoon's motion, and his investigations of the Earth's magnetic field and of tides were unrialled for centuries. His prediction of the transit of Venus led to Cook's voyage to Tahiti. He was far more than an cloistered academic; his exploits as a naval captain led to perilous adventures, and he wasalso a notable servant of the State. Much material about his eventful career has come to light in recent years, making this a timely new account of the life, scientific interests, and continuing influence of this engaging and adventurous scholar. Sir Alan Cook has written a fascinating andilluminating account of Halley's life and science, making this a unique and highly readable biography of one of the key figures of his time.

For most people, Edmond Halley is best known for accurately predicting the periodic appearance of the comet that ultimately would bear his name. But his greatest achievement may have been overlookedâ€" indeed few people know that it was Halley who solved the riddle of accurate navigation for all sea-going vessels. As seventeenth-century scientists gradually came to believe that the inside of the Earth was magnetized they were puzzled by the fact magnetic north not only varied slightly from place to place, but gradually changed over time, suggesting a slow variation of the Earth's magnetic field. But if the Earth was permanently magnetized, how could its magnetism vary? Edmond Halley, Britain's Astronomer Royal, ingeniously proposed that the Earth contained a number of spherical shells, one inside the other, each magnetized differently, each slowly rotating in relation to the others. This brilliant deduction earned Halley the command of a small sailing ship, the 52-foot Paramore, and with it, a royal mandate. Halley was to sail forth "to stand so far into the South, till you discover the Coast of the Terra Incognita." But more importantly, determine the variation between true and magnetic north in order to more accurately calculate longitudeâ€"a feat that would improve Britain's navigational skills and ensure its dominance of the high seas. Halley's Quest takes readers on a trilogy of sea voyages, each of which proved to be as novel and revealing as it was difficult and controversial. But more than a yarn of risk and adventure, the story at the core of the book is a deeply personal and intellectual tale that captures the science and the spirit of an almost forgotten episode in the history of navigation. Once branded a heretic by the Church and denied a prestigious scholarly chair at Oxford University, Halley ultimately changed the course of science, producing charts that described more accurate ways to navigate and documenting new geophysical phenomena ranging from ocean patterns to the motion of Jupiter's moons. This delightful book emphasizes the drama of Halley's mission and the passion of an era hungry for the stories science had to tell.

Since its launch in 1987, the History of Cartography series has garnered critical acclaim and sparked a new generation of interdisciplinary scholarship. Cartography in the European Enlightenment, the highly anticipated fourth volume, offers a comprehensive overview of the cartographic practices of Europeans, Russians, and the Ottomans, both at home and in overseas territories, from 1650 to 1800. The social and intellectual changes that swept Enlightenment Europe also transformed many of its mapmaking practices. A new emphasis on geometric principles gave rise to improved tools for measuring and mapping the world, even as large-scale cartographic projects became possible under the aegis of powerful states. Yet older mapping practices persisted: Enlightenment cartography encompassed a wide variety of processes for making, circulating, and using maps of different types. The volume’s more than four hundred encyclopedic articles explore the era’s mapping, covering topics both detailed—such as geodetic surveying, thematic mapping, and map collecting—and broad, such as women and cartography, cartography and the economy, and the art and design of maps. Copious bibliographical references and nearly one thousand full-color illustrations complement the detailed entries.

This exciting Greenvill Collins biography is about seventeenth century navigation, focusing for the first time on mathematics practised at sea. This monograph argues the Restoration kings’, Charles II and James II, promotion of cartography for both strategy and trade. It is aimed at the academic, cartographic and larger market of marine enthusiasts. Through shipwreck and Arctic marooning, and Dutch and Spanish charts, Collins evolved a Prime Meridian running through Charles’s capital. After John Ogilby’s successful Britannia, Charles set Collins surveying his kingdom’s coasts, and James set John Adair surveying in Scotland. They triangulated at sea. Subsequently, Collins persuaded James to sustain his dead brother’s ambition. This, the British coast’s first survey took six years. After James’s flight, and William III’s invasion, Collins lead the royal yacht squadron for six years more, garnering funds to publish Great Britain’s Coasting Pilot. The Admiralty and civic institutions subsidised what became his own pilot. Collins aided Royal Society members in their investigations, and his new guide remained vital to navigators through the century following. Charles’s cartographic promotion bloomed the most spectacularly in the atlases of Ogilby, Collins and John Flamsteed for roads, harbours, and stars.

Traces the impact of world events on St Helena's topography, ecology and human population, from the early 1500s to the present day. Since its discovery in the early 1500s, St Helena - though remotely situated - has repeatedly participated in events taking place on a world stage; evidence of those encounters is etched on the topography, ecology and human population of the island. This book examines the impacts of a century of casual but destructive visits from sailing ships of various nations followed by settlement by the East India Company; the fortification and population of the island by the Company, including the importation of an enslaved population; efforts to make it economically self-reliant; its employment a base for scientific observations from Edmond Halley to Joseph Hooker and beyond; its role as a prison-fortress from Napoleon to the twentieth century and as a base for anti-slavery patrols in the South Atlantic following the Abolition of Slavery; its decline since the end of the days of sail; measures taken to reconnect it with the modern world in terms of sea and air travel as well as electronic communication; and efforts to regain to some degree the ecological diversity of the virgin island setting.
