Engravings
Diagrams and engravings play an important role within A Compendious System of Astronomy as they provide a new level of clarity to the reader. Bryan diagramed the constellations of the Northern Hemisphere to provide an added level of clarity and visual aid to her readers. Following the theme of the northern hemisphere, she also diagramed the different zones of the sky as seen from Earth. All of her engravings are original and drawn by Bryan herself. The diagrams serve as memory aids for students and help to give an additional level of senseory detail to the student and reader. As pictured, Bryan details the stars in each constellation and goes as far as to outline the how the constellations should look to the average person.
