The relationship between distance and time. How to navigate using landmarks and lights. Short description of set and drift.
Before GPS, before Loran, before the sextant, before the astrolabe, before the cross-staff the perception of time was very different than it is in today’s modern mind. Time has changed, at least the way we perceive time. What time is it? Is a modern concept of specificity. Time is essentially a mind exercise in incrementality. At the beginning years of civilization time was thought of in two increments, the sunup the sundown and the seasons; planting, growing, harvesting, and wintering. The language of time before clocks was a language pocked full of references to distance. The average person understood distance more clearly as an increment.
