CHEVALLIER, Reverend Temple. Wrote a description of the meridian line drawn in the cloister of Durham Cathedral which was delineated in 1829 by Mr William Lloyd Wharton, of Dryburn, and Mr Carr, then Headmaster of Durham School. Because of the the difficulties of the site the meridian line is partly on the pavement of the cloister, and partly upon the south wall, thus the summer indications are on the floor, and the winter indications upon the wall. Durham, late 19th century.

CHRISTIE'S, Maritime Sale 9th May 1996. Sales catalogue with details of the Swan Hunter sundial designed by J. Wigham Richardson. "Item 149 - The sundial of painted wood (in two pieces), with metal gnomon, originally mounted above the main gate of Neptune Shipyard - 32« x 28Å in. (88-3 x 72-4 cm)". Historic information and drawing. Purchased by Charles K. Aked and presented to the Maritime Museum, Newcastle-on-Tyne. The dial was repaired before despatching it. See BSS Bulletin 96.3, pages 29-31 for further details, and correspondence.

CHRONOMETROPHILIA. This journal is produced in La Chaux-de-Fonds, the texts are generally in French or German. The articles on sundials included in the journals produced to date are given in this list under each author's name. The articles are of a very high academic standard and generally on aspects not written about previously, hence these are of great importance. In general the Continental enthusiasts have displayed more interest in the subject of gnomonics and are much better informed than the English diallists.

CLARK, Latimer. Manual of the transit instrument and use for obtaining accurate time. Chicago, 1880 XXII, 259, 85-92, March 1880. “Sunshine and the Various Modes of Observing and Registering it”. This a report of a lecture given by Mr G M Whipple, Superintendent of the Kew Observatory, to the British Horological Institute at Northampton Square. He excused himself for not opening with an account of sundials since he thought he would be in the position of Aesop’s Ass in the Lion’s Skin, and soon detected for his braying in front of so many important authorities on the horological art. The lecture thus amounted to an account of the state of knowledge of the sun in 1880, when even the source of the sun’s output of heat could not be explained since there was no knowledge of atomic fusion then . See Chandler, for data on sunshine hours in London.

This is a translation into Italian of the Latin text of the Englishman John Holywood, known as Johannes de Sacrobosco [John Holywood]. It is a short treatise on dialling in a book devoted to mathematics and cosmography, being pages 374-382, intended to show how mathematics could be applied to practical use.

CLERKE, Gilbert. The Spot Dial. One of Clerke's neighbours wanted to have a ceiling dial, so this pamphlet was written in response to the request. It contains very detailed instructions for an ordinary person to make a reflecting dial. Reflecting dials were very popular at this period. 1687. Gilbert Clerke (1626-1697?) was educated at Sidney House College, Cambridge, and remained as a tutor for a short time, resigning after a difference of opinion with the authorities. He went to live on a small estate inherited from his father and there taught mathematics privately. He wrote a book on the art of dialling, published in Stamford, Lincolnshire; and executed commissions in dialling.

CLOCKMAKERS' COMPANY, The Library of the Company of Worshipful Clockmakers has many works on dialling and these are listed separately in the index of The Clockmakers' Library - The Catalogue of the Books and Manuscripts in the Library of the Worshipful Company of Clockmakers, compiled by John Bromley. London, 1977. There are many previous catalogues of the Clockmakers' Library, there is little difference in the contents except for new acquisitions. Of interest is the print 'The very extraordinary sun dial facing the market place at Settle, Yorkshire', an engraving by S. Buck and I. Feary. 42 x 53 cm. 1778. Several of these catalogues, including the one listed here, are the library of C. K. Aked. Occasionally the Clockmakers' Company sells items out of its collections.
