The anonymous compiler (possibly the engineer and alche- mist Ralph Rabbards) combined practical experience of Italian military campaigns with fanciful ideas for adapting ancient inventions — among them, an ingenious design for a wetsuit with adjustable snorkel, for covert attacks on enemy shipping. The tension between learning and expe- rience, speculation and utility, can also be detected in scholarly works. When John Dee famously surveyed the “Artes Math- ematicall” in his preface to Henry Billings- ley’s 1570 English translation of Euclid, he stressed the value of mathematics in study- ing both natural phenomena and practical problems — from arranging to com- pounding medicines. The utilitarian ethos helps to explain why Digges, for all his astro- nomical skill, served Elizabeth primarily by consulting on the construction of Dover Harbour. Dee, who coined the term “Brytish Elizabeth I rests her hand on a — an instance of technology advertising naval prowess.
