First edition of Doppelmayr's important astronomical work in attractive contemporary colour, extra-illustrated with 2 additional engraved plates. The plates depict celestial charts with diagrams, tables and views of observatories and were intended as an introduction to the fundamentals of astronomy. 'Besides being a star chart and a selenographic map, the Atlas includes diagrams illustrating the planetary systems of Copernicus, Tycho, and Riccioli; the elliptic theories of Kepler, Boulliau, Seth Ward, and Mercator; the lunar theories of Tycho, Horrocks, and Newton; and Halley's cometary theory.' (DSB IV, p.166). The additional plates, both published in 1747, anticipate the solar eclipse of 25 July 1748 based on the calculations of Swiss mathematician Leonhard Euler. Shirley, BL C.Dop.-1c.
