John Collins (1625-1683) began his career as a bookseller's apprentice, but his path took an unexpected turn with the onset of the English Civil War. During the conflict, Collins joined an English merchant ship and spent seven years in the Mediterranean. In his spare time, he studied mathematics and merchant accounting, gaining the skills that would later help him establish himself as a teacher upon returning to London. In 1659, Collins published The Mariners Plain Scale New Plain'd for the use of the British East India Company's navy. Prior to this, Collins had written treatises for his personal students, but this publication was well-received, eventually being incorporated into the curriculum for British sailors. The present treatise introduced new methods for measuring a ship's course or distance using the plain scale -- a term first recorded by the Oxford English Dictionary in the present work; a divided line indicating the scale (i.e., its relation to real distance) of the chart -- as well as navigating currents, calculating "circle sailing," and performing arithmetical navigation. Collins was elected a fellow of the Royal Society in 1667 and continued to advance navigational techniques throughout his life. He was a contemporary of Isaac Newton and John Wallis, and remains a key figure in the Scientific Revolution in Britain. The present example includes the title of the composite volume and title pages for all three parts (including the title for the first part) Navigation by the Mariners Plain Scale new plain'd: or, a Treatise of Geometrical and Arithmetical Navigation. (ESTC R207824); most examples that have sold have this configuration. Theodore "Ted" Benttinen (1948-2023) was an MIT-educated oceanographer and explorer who went to both poles on research missions. Benttinen amassed a formidable collection of books of exploration, particularly strong in Pacific voyages as well as in polar accounts. The present volume was lot 54 in the Sotheby's New York 9 December 2024 sale of his library. ESTC R171445 & R207824; Tomash & Williams, History of Computing C124-126.Catalogued by GR Murdock.
