2 - Sailing the Oceans and Seeking Longitude before 1714

Summary

This chapter explores the long- and short-term roots of the British Longitude Act 1714, highlighting the degree of continuity with earlier precedents. It first explores the nature and impact of developments in navigational techniques and instruments, astronomy, timekeeping, the finding of longitude on land and the judging and funding of longitude proposals in sixteenth- and seventeenth-century Europe. It then delves into the chain of events and written and verbal discussions which gave rise to the new British rewards in 1713–1714. These saw the self-interested lobbying of two projectors gain momentum through a confluence of national and political interests, before becoming enshrined in law as rewards open to all comers.
