Lost at Sea exhibition material

This article offers descriptive list of some of the items included in Lost at Sea: The Ocean in the English Imagination, 1550-1750, one of the Exhibitions at the Folger.

Tools for Finding Yourself at Sea

These exhibition materials focus on the tools English mariners and writers used—from atlases, sextants, and star charts to prayer-books, symbols, and stories—to find themselves on changing oceans.

Maps

Charts and maps were among the most basic tools for locating oneself at sea.

The Mariner’s Mirrour began as a groundbreaking Dutch atlas, but Anthony Ashley’s translation transformed it into an English book. The image on the title page shows many tools of the mariner’s trade, from upward-oriented celestial instruments including quadrants and astrolabes to downward-oriented lead lines that were used to measure the depth of a harbor. The English edition also places the English nation at the center of the maritime world by mentioning Sir Francis Drake. The Folger’s hand-colored copy, which is currently unbound and undergoing conservation, would presumably have been intended as a lavish gift, perhaps for one of the wealthy private families who helped underwrite English navigation.

Early modern maritime atlases were not used only by navigators and pilots. They were also aesthetic objects, designed to display early modern Europe’s changing vision of the world. This engraving of the New World was first published in 1617, and it was revised over the years. The example shown here comes from a Dutch atlas published in 1642, and hand colored at a later date. Close-up maps along the top feature major cities such as Havana, Cartagena, Cusco, and Rio de Janeiro. The vertical columns framing the map provide a mini-ethnography of native peoples, including Brazilians, Mexicans, Floridians, Virginians, and Greenlanders.

Instruments

Determining one’s position at sea required expertise in using many complex instruments, including celestial, magnetic, and mechanical devices.

John Davis, captain of three Arctic voyages, combined mathematical skill with practical nautical experience. In 1594 he invented the “Davis Staff,” an important instrument which would be widely used for measuring the altitude of the sun. Davis reversed the traditional cross-staff, so that the sailor measured the shadow the sun cast on the staff rather than staring directly at the sun itself. This image in Davis’s book of maritime instruction represents a fairly simple early version of the staff, which would be refined and used into the eighteenth century.

Samuel Sturmy intended his lively volume to educate his brothers, sons, and any other young men who wanted to go to sea in seventeenth-century England. Drawing on his own experience in a career spent traveling from Bristol to Virginia and the West Indies, it presents clear instructions that could be used with no greater mathematical knowledge than arithmetic. The volume also contains instructions for using navigational instruments, such as this nocturnal, which was designed to use the altitude of a given star to compute time at night.

Sermons and Prayers

Early modern believers and theological writers represented the sea as a space of divine power and revelation.

The clergyman James Janeway’s publications typified seventeenth-century efforts to combine realistic sea-stories with Providential theology. In A Token for Mariners, Janeway brought together accurate historical narratives with Providential interpretations. He also provided ready-made prayers and sermons for events at sea, from shipwreck to victory in battle. This image shows a shipwreck in the Providentialist view: the ship is in danger, the men are clinging to a broken mast, but the eye of God looks unblinking down to control everything.

Preachers often sought to reveal the secrets of the deep, and one anonymously published volume took the claim literally. Vox Piscis, or The Book-Fish consists of three theological treatises supposedly discovered in the belly of a recently-caught codfish. The tracts were actually reprints of radical writings by the sixteenth-century martyr John Frith. Placing Frith’s words in the fish’s belly transformed them into divine wisdom from the bottom of the sea. From the belly of the cod came a nonhuman voice proclaiming God’s will to an England that was again becoming divided by religion.

Science and Mathematics

Advances in cartography and navigation helped drive new scientific understandings of the maritime world.

A self-educated writer and mathematician who lived among sailors at Gravesend on the Thames, William Bourne wrote A Regiment for the Sea for practical mariners. His text was not original; Bourne adapted Richard Eden’s Arte of Navigation, which itself was a translation of Martín Cortés’s Arte de Navigar. But unlike both Eden and Cortés, Bourne wrote for sailors, not navigators. By using his book, all mariners could learn to orient themselves by the stars and other maritime technologies.

After being appointed the first surgeon-general of the East India Company, John Woodall published The surgeons mate, or, Military & domestique surgery in 1617 as a comprehensive reference manual and teaching guide for maritime surgeons. The book contained the first suggestion that scurvy could be prevented by using lemon juice, though this practice did not become widespread until the end of the eighteenth century, much to the detriment of English sailors.
