Ac licet utriusque sideris conversiones et motus, ut scrutatores causarum intellegibilium adverterant, in unum eundemque finem, lunari cursu impleto, perenni distinctione conveniunt, tamen sol non semper his diebus obducitur, sed cum luna e regione (velut libramento quodam igneo) orbi et aspectui nostro opponitur media.
And although the revolutions and movements of both heavenly bodies, as the searchers for intelligible causes had observed, after the course of the moon is completed, meet at one and the same point always at the same distance from each other, yet the sun is not always eclipsed at such times, but only when the moon (by a kind of fiery plumb-line) is directly opposite the sun and interposed between its orb and our vision.
