A Double Horizontal Sundial by George Cooke

This article analyses and describes the restoration of a rare double horizontal sundial signed by George Cooke, an apprentice of Elias Allen, dating to ca. 1645–47. Geometric analysis determines the design latitude as 53º N, and XRF analysis confirms the use of lower quality brass, suggesting it was possibly a 'master-piece' or early instrument.
