Epitome astronomiae copernicanae, usitatâ formâ quaestionum & responsionum conscripta, inq; VII. libros digesta ..
Johannes Kepler's 1618 Epitome of Copernican Astronomy, printed at Lentijs ad Danubium, is a question-and-answer treatise on astronomy for students and scholars. Its pictures are geometric diagrams of circles, radiating lines, and lettered points, showing planetary orbits and eccentric motion in a clean, precise woodcut style that a designer could take as a model for structured, labelled line diagrams.
