A 50-minute workshop on Medieval Navigation. Beginning with the basics of “saying” the compass and the organization of time aboard Medieval European vessels, Simon will teach the principles of dead reckoning, supervising the participants as they use reproduction traverse boards. After discussing the sources of error in dead reckoning, Simon will de-mystify the principles of celestial navigation, and participants will measure the angle of a “star” with reproduction plumb-line quadrants. Simon will explain how and why the 15 th -century Portuguese developed the noon sight of the sun; weather permitting, the class will step outside and measure the angle of the sun with reproduction astrolabes. The class will be fast-paced and somewhat technical. No prior knowledge or experience of navigation or astronomy is required. The class can accommodate up to twelve participants easily; by sharing the reproduction instruments, up to 30 people could participate.
