In his photographic and systematic map of the moon, Charles Le Morvan used original pictures of the photographic atlas of the moon by Loewy and Puiseux published between 1896 and 1910 by the Paris Observatory, a work in which he participated. Le Morvan’s atlas was produced using the same apparatus at the Observatoire de Paris as Loewy and Puiseaux’s. In his preface Le Morvan points out that his atlas is ‘intended as a supplement to its great, but incomplete precursor entirely composed of [previously] unpublished proofs, for which a most proper format and disposition has been chosen to assure an overall maximum manageability, without sacrificing indispensable quality, precision and accuracy, which would have been compromised by further reduced dimensions."
The ‘Carte photographique et systématique de la Lune’ comprises two parts. 48 beautiful photogravures by L. Massard in 6 folio booklets 50.5 x 38.5 cm (average size of photos: 32 x 25.5 cm.) A second publication appeared in 1926, with 6 boards showing live images of the lunar disk at different times (first quarter, full moon, etc.).
