William Oughtred, Richard Delamain and the horizontal instrument in 17th-century England (1981)


Description The author describes an instrument based on stereographic projection which could be used both for time-measurement and for solving problems concerning the position of the sun. When the horizontal instrument was first published in England, it became the subject of a violent priority dispute. The dispute is described, and the history of the instrument in 17th-century England is recounted. The paper concludes with a checklist of surviving examples.
