Alle Thyng Hath Tyme recreates medieval people's experience of time as continuous, discontinuous, linear, and cyclical--from creation through judgment and into eternity. Medieval people measured time by natural phenomena such as sunrise and sunset, the motion of the stars, or the progress of the seasons, even as the late-medieval invention of the mechanical clock made time-reckoning more precise. Negotiating these mixed and competing systems, Gillian Adler and Paul Strohm show how medieval people gained a nuanced and expansive sense of time that rewards attention today.
