[ Nineteenth-century Swiss architecture. ] Volume of 'Skizzen & Notizen' by 'G. Samuel Senn', containing numerous original architectural tracings, diagrams, illustrations, calculations, and manuscript text 'Bauvertrage, Akkörde und Akkordbedingungen'

Around 280pp., small 4to (20.5 x 16 cm). In bulky notebook with marbled boards and label on front cover: 'Skizzen & Notizen | von | Samuel Senn. | 1848.' Internally in fair condition, shaken, on aged and worn paper. In heavily-worn binding with spine almost rubbed away and front cover coming loose. An attractive and impressive volume, crammed with detailed tracings, diagrams, illustrations and plans of architectural features, projections, patterns and ornaments, most in fine pen and a few in colour. Most of the tracings have been laid down, with a few folding out. Also illustrations of statues, views of churches, castles and other buildings, as well as work in wrought iron (including gates and lamp posts) and stone. Inside the front and back covers are striking and amusing silhouette drawings of devils at play. The first couple of pages carry stamps in black ink of Bauverwaltung, Zofingen. Less than a quarter of the volume consists of text in German, with construction notes, price lists, tables, several of the later entries being signed 'Wolff'.
