A Sundial at the Bodleian Library in Oxford

This article investigates the historical existence of a sundial on the south wall of the Bodleian Library, depicted in Loggan's 1675 drawing and a later 1818 engraving. It provides evidence for its reality, discusses its disappearance by 1814-1880 due to redundancy and weathering, identifies Richard Hawkins as its painter in 1641, and suggests its original positioning.
