Specialist Notes
Extensive and detailed treatise on Gnomonics, beautifully illustrated , structured in five parts (Caput):
Caput I - Principij Mathematicis & nbsp; (8 praxis) < / p> Caput II - Doctrina Sphaerica & nbsp; (2 praxis)
Caput III - De variorum horologiorum in plano description & nbsp; (Propositio I-XIII)
Caput IV - De Horologijs orientalibus declinantibus & nbsp; (Propositio I-II) - & nbsp; Divided into various parts and chapters
Adiiciuntur nonnulla alia non minus utilia quam iucunda , fromp.126 to 144.
This last part contains perhaps the most interesting and illustrated section, the one dedicated to the & nbsp; De Horologio Nocturno , divided into 5 Propositio and enriched by & nbsp; no less than 13 illustrations, figures and reconstructions with volvelle and movable parts . < / p>
As an interdisciplinary science, Gnomonics integrates mathematics, philosophy, art, history, astrology, astronomy, cosmography etc. All this is splendidly represented and collected here, in a rigorous scientific treatment that starts from the mathematical assumptions of the discipline and then declines its forms in theoretical but also and above all practical aspects, proposing itself primarily as a useful treatise for the construction of sundials and night clocks. . Each aspect is examined in detail and proposed to the reader so that he can understand the ratio and reproduce the object, with the constructive purpose that Gnomonics has always proposed. A treatment that, although not original, also assumes an artistic and aesthetic value in the perfect and accurate design of the celestial spheres, meridians, verticals, astronomical horizons and finally the various parts of the clocks.
