Reference drawing
The book “Kurtzgefasste Einleitung zur Perspectiv” written by Bischof Johann Christoph consist of five different main parts. The first few pages are a preface to the reader. Subsequently the second part is the main text called “brief introduction to perspective”, even if it fills 134 sites of the book. The next part is the attachment of the book and writes about the preparation and use of paints. The following part is the called “register of the finest things”. The last part of the book consists of a collection of technical drawings.
The last category of the book, with the technical drawings, is linked with the main text “brief introduction to perspective”. All the topics the main text explains, are illustrated in those different pages.
The drawings are divided into 31 smaller parts which are marked with “Tab + number” and a frame around the part. The parts themselves consist of several drawing called “figures”. In total there are 102 different figures. So, the text refers to a Tab and then to the corresponding figure.
Each one of those Tab’s is drawn on a different, bigger paper. Those 31 papers are folded and inserted at the end of the book. This allows the pages with the figures to lie straight, when the book is opened. Also, with this method the arrangement of the different Tab’s is very clear and ordered. You can easily find what the text refers to or what you have been searching for and also, you would have enough space to take your own notes or make additions next to the correspond figure.
The drawings are very important in this book because they illustrate the instructions in the text and also make it easier to understand it.
The first figures are simple 2D geometry objects like a square, a triangle or a circle and how to draw them in different perspectives. As you scroll further, the figures become more complex and also more architectural like a cross vault and its floor plan. Also, the figures become 3D, for example a cube or a pyramid. The figures are more complex now and show different stair sets or arcades. The next topic consists of different kinds of columns and their parts. Tab 20 refers to drawing open windows or doors. Tab 21 and 22 show how to draw chairs and tables. The last category concentrates on drawing objects and their shadows with the different incidence of light.
