The dissimilarity in style, subject, feeling and in many cases media of most of the drawings on the versos of this sketchbook lead the cataloguer to believe that these were executed at the end of the 1940s when Moore was jotting down ideas for Prométhée (see HMF 1196). This is further supported by the fact that several of the supposedly later sketches were made over offset images from the 1935 drawings, and that the inscriptions are compatible with Moore's handwriting of the early 1950s. Finally and conclusively, many of the later drawings can be linked with sculptures of that period, such as Draped Reclining Figure LH 336 and Time-Life Screen LH 344, both completed in 1952-53.
