Description
A pyramidal dial, the centrepiece of King Charles II’s Garden in Whitehall in 1669. The dial is mounted on a pedestal and consists of six tiered levels. Decorative iron branches project from each level, each supporting a different glass dial.
Plate 31 from William Leybourn’s Dialling: plain, concave, convex, projective, reflective, refractive… (Black Swan, Pater-Noster-Row, 1690)
Written in the associated description: ‘each of them [branches] carrying a Glass Bowl […] on which Bowl are also Dials described, but different from the former, shewing the hour according to the several ways of counting the Hours. These Bowls are painted on the inside with thick Colour to keep out the Light, except a little place which is left clear, like a Star, for the Sun Beams, to pass thorow and shew the Hour’
William Leybourn (1626-1716) British mathematician and land surveyor was not a Fellow of the Royal Society.
