Question 84. Why do they take the beginning of the day from the midnight? Solution. Is the reason that the commonweal had a military constitution at the first? For many matters of concern on military expeditions are managed by night. Or did they make sunrising the beginning of business, and the night the preparation for it? For men ought to come prepared to action, and not to be in preparation when they should be doing,—as Myso is reported to have said to Chilo the Wise, when he was making a fan in winter. Or as the noontide to many is the time for finishing public and weighty affairs, so did it seem meet to make midnight the beginning? This hath this confirmation, that a Roman governor would make no league or confederation in the afternoon. Or is it impossible to take the beginning and end of the day from sunrising to sunsetting? For, as the vulgar measure the beginning of the day by sense to be the first appearance of the sun, and take the first beginning of the night to be the complete withdrawment of the sun from sight, we shall thus have no equinoctial day; but the night which we suppose comes nearest in equality to the day will be manifestly shorter than the day by the diameter of the sun. Which absurdity the mathematicians, going about to solve, have determined that, where the centre of the sun toucheth the horizon, there is the true parting point between day and night. But this contradicts sense; for it must follow that whilst there is much light above the earth, yea, the sun illuminating us, we will not for all this confess it to be day, but must say that it is still night. Whereas then it is hard to take the beginning of the day from the rising and setting of the sun, by reason of the forementioned absurdities, it remains to take the zenith and the nadir for the beginning. The last is best, for the sun’s course from noon is by way of declination from us; but from midnight he takes his course towards us, as sunrising comes on.
