Angel with a Sundial Photographed at 11 am, Chartres Berthier, Paul Marcellin  (French, 1822-1912)

“An icon of photomechanical reproduction.” Rosen

The image is of angel holding a sundial, which is inscribed with the date 1578. The image was chosen perhaps because the sundial aligns photography with the primitive clock, in that the raw materials for both the medieval sundial and the camera are sunlight and the passage of time. Or was it that the sundial made from stone was able to withstand the test of time as would be the photograph reproduced in printer’s ink? Or both? Whatever the reason, the sundial image quickly became the image used by inventors as a trial image to demonstrate new processes of reproduction.

This privileged role of
L’ange in early photomechanical printing began with the development of photolithography by the print magnate Rose-Joseph Lemercier and his collaborators Lerebours, Barreswil and Davanne. Lithophotographie, as it was called at the time, was first reported to the Académie des Sciences on June 28, 1852 – just months after Le Secq made L’ange. Lemercier and crew continued to work on the process well into the next year, printing proofs to show to photographers and industrialists. While they reproduced many of Le Secq’s photographs, Lemercier chose as his signature image the view of L’ange. The print was included in a portfolio titled Lithophotographie, ou impressions obtenues sur pierre à l’aide de la photographie which was distributed to industrialists across Europe in 1853. L’ange was also featured as the first photomechanical image included in a printed journal in an 1854 issue of Bulletin de la Société d’encouragement pour l’industrie nationale.

After 1854, the image was printed in numerous photomechanical processes by different inventors. At the Exposition Universelle of 1855, "L’ange portant le cadran solaire" was displayed in three different locations, each representing three different graphic processes: the same image was exhibited as a salted-paper print, as a photolithograph, and as an image transferred onto a zinc plate called "litho-typo-gravure." Alphonse Poitevin, who introduced a rival process of photolithography in 1856, also used the same view of Chartres for one of his early reproductions. By the 1870s, LeSecq’s "L’ange portant le cadran solaire" was again reissued by the printer Thiel in a new series of photolithographs made as yet another printer’s portfolio.

On December 1, 1855, La Lumiere published a new photomechanical process by Dumont and a gravure to illustrate the process. Called zincographie galvanique, Dumont’s process transformed photolithographs into typographically-reproducible plates. The gravure used to accompany the article reproduced Lemercier’s print of the L’ange. Any mention of Le Secq as the author of the original photograph was omitted, as if this information was not relevant to the new printing technique sampled. La Lumiere praised the new invention and the print as the first means capable to print text and photograph together by letterpress.

Another copy of this print was registered with the Dépôt Légal in 1856. See DL, 1856, nos. 3843 and 3844, in Eo64, no. 12, Cabinet des Estampes et des Photographies, Bibliothèque Nationale de France. See also Rosen, “Lemercier et Cie,” (1988): 30, 307. Lewis p. 366
