Medieval Horology & Such
Horology lit. "the study of time" is the art or science of measuring time. Clocks, watches, clockwork, sundials, hourglasses, clepsydras, timers, time recorders, marine chronometers, & atomic clocks are all examples of instruments used to measure time. In current usage, horology refers mainly to the study of mechanical time-keeping devices, while chronometry more broadly includes electronic devices that have largely supplanted mechanical clocks for the best accuracy & precision in time-keeping.

SHADOW OF NIGHT real-time reading, 8 April 1591 (Chapter 30): "Master Habermel stopped by. Your compendium is on the table." You may recognize parts of Diana's compendium in the images below. The first image was not by Habermel, but another period instrument maker named Johann Anton Linden, and it provided me with the general structure of Diana's compendium, onto which I projected Habermel's style. ` Deborah HArkness facebook
