DSB XIV, p.446; Houzeau & Lancaster 9232; Wing W2986. - First edition. "Like many astronomers in the second half of the seventeenth century, Wing, following Boulliau and Seth Ward, opted for an 'empty-focus' variant of Kepler's second law, holding that a planet moving in an elliptical orbit describes equal angles in equal times about the focus not occupied by the sun. In works published in 1651 and 1656 Wing, adopting Boulliau's method, had his elliptical orbits, including that of the moon, generated in purely geometrical fashion by circles and epicycles.
In his posthumously published Astronomia Britannica, however, he discarded the epicycles in favour of a refined version of the theory proposed by Ward in the latter's Astronomia geometrica (1656), in which the elliptical orbits were assumed to be physically generated. Wing's celestial mechanics contained a mixture of Cartesian and Keplerian components, with a rotating sun and celestial vortex pushing the planets around in their orbits" (DSB XIV, p.446).
