This paper considers a group of three fourteenth-century English horary quadrants with links to King Richard II and the highest nobility. Building on previous work by Silke Ackermann and John Cherry, it shows how this group of instruments can tell us much about the overlapping significances of medieval instruments-which might at the same time have practical purposes and political significance.
