Quod alias non evenit ita perspicue, nisi cum post inaequales cursus iter menstruum lunae ad idem revocatur initium, certis temporum intervallis, id est cum in domicilio eiusdem signi tota reperitur luna sub sole, liniamentis obiecta rectissimis, atque in his paulisper consistit minutis, quae geometrica ratio partium partes appellat.
This phenomenon never takes place so clearly as when the moon, after its shifting courses, brings back its monthly journey to the same starting-point after fixed intervals of time; that is to say, when the entire moon, in the abode of the same sign of the zodiac, is found in a perfectly straight line directly under the sun, and for a brief time stands still in the minute points which the science of geometry calls parts of parts.
