SELWYN COLLEGE CAMBRIDGE – VERTICAL DIAL

DIAL

BRITISH SUNDIAL SOCIETY RECORD

The dial is mounted on the north range of Old Court just above ground floor window level, to the right of staircase D, and declines about 4° west of south. It was designed by Frank King and made by the Cardozo Kindersley workshops in Cambridge. It has Babylonian and Italian hour-lines (showing hours since sunrise and since the previous sunset). The hours are read from the shadow of the brass nodus ball (this type of dial does not require a polar-directed gnomon). Across the top section of the dial, above the winter solstice curve, is a rising sun with the inscription ’ΚΑΙΡΟΝ ΓΝΩΘΙ’ (Know the time). Across the lower part, below the summer solstice, is inscribed ’Collegio suo / lactarius Eboracensis / me dono dedit’ (To his college the Yorkshire dairyman gave me as a gift). Around the rim of the dial are inscribed ’Babylonian hours since sunrise’ and ’Italian hours since sunset’. Ref: BSS Bulletin 22(iii), Sept 2010, pp 2-8, and 22(iv), Dec 2010, pp 9-11.

The use of the Greek motto reflects strong historical links between the College and Ely Cathedral, where the motto is also used. My recent piece on the Cathedral can be seen HERE.

CHRIST’S COLLEGE CAMBRIDGE: Vertical Dial – Sic Transit Gloria Mundi

Published on June 5, 2023 by Rolling HarbourLeave a comment

The sundial is located on the wall of the Hall, and – for those not entitled to enter the College – easily visible from the entrance by the Porters’ Lodge. It is dated 1927, replacing a dial known (from an old print) to have been in this position in C17 that was lost during C19 alterations to the Hall. The dial was the gift of a College benefactor. His initials and the year of installation are on the dial supports. The calculations were carried out by a Member of College who was a sundial expert.

The unequal positions of the hour markers take account of the SW aspect of the wall, showing more afternoon than morning hours for accuracy as the sun declines.

MAGDALENE COLLEGE . CAMBRIDGE – Double Vertical Dial 1987

Published on April 16, 2023 by Rolling HarbourLeave a comment

I recently came across a very bad photo I took years ago of this elegant and ingenious dial in Magdalene College. My image is too awful to be the basis of a feature. However BSS has in its records this excellent quality photograph with a short account to accompany it.

A competition among first year engineering students led to the creation of this most striking double vertical dial, mounted in 1987 on the south-facing wall of Benson Court. It was designed by Will Carter in stone and stainless steel and features the motto: ‘Facilius inter philosophos quam inter horologia conveniet.’ (It is easier to gain agreement among philosophers than among timepieces – Seneca) The prize-winning design has the Equation of Time built into the gracefully curving hour lines. A spot of light shining through a pierced stainless steel sun marks the time on each dial.
