Reinventing Time

This unit looks at the various types of objects used to keep time since antiquity. It is based on a lecture by Philipp Nothaft, delivered in 2019 for the undergraduate course, 'Technology and Culture in Global Perspective, 1100–1700', (History Department, University of Oxford), with additional materials contributed by Howard Hotson in 2021.
