On page 9 of Bartlett’s 1986 sketchbook, the artist depicts five thumbnail sketches for what would become the central paintings of his Au Temps series. The artist has placed titles under each of the thumbnails and annotated the top thumbnail with measurements regarding the size he wanted all five of the paintings to be.
The top thumbnail titled Life depicts a house centrally located with figures seen on the left side of the frame. This painting became Object Permanence. The next thumbnail below Life is titled Resurrection Flight and it became Resurgere e Renasci. The thumbnail below Resurrection Flight is titled Airplane and it became Tarmac. The bottom two thumbnails are Death and Road, respectively, and the only title change of the two was Road, which became Damascus Road.
