Sunne goeth not farre vnder the horizon, that by the light of the Moone and
Starres we may trauell all night, and if occasion were, do some other
labour also. And there is no man that doubteth whether our cattell can see
to feed in the nights, seeing we are so well certified thereof by our
experience: and by reason of the sphere our nights should be darker then
any time vnder the poles.

The Astronomers consent that the Sunne descending from our vpper hemisphere
at the 18 parallel vnder the horizon maketh an end of twilight, so that at
length the darke night insueth, and that afterward in the morning the Sun
approching againe within as many parallels, doth driue away the night by
accesse of the twilight. Againe, by the position of the sphere vnder the
pole, the horizon, and the equinoctiall are all one. These reuolutions
therefore that are parallel to the equinoctiall are also parallel to the
horizon, so that the Sunne descending vnder that horizon, and there
describing certaine parallels not farre distant, doth not bring darke
nights to those regions vntill it come to the parallels distant 18 degrees
from the equinoctiall, that is, about the 21 degree of Scorpio, which will
be about the 4 day of our Nouember, and after the Winter solstitium, the
Sunne returning backe againe to the 9 degree of Aquarius, which will be
about the 19 of January; [Sidenote: The regions vnder the poles want
twilights but sixe weeks.] during which time onely, that is, from the 4 day
of Nouember vntill the 19 day of Ianuary, which is about six weeks space,
these regions do want the commodity of twilights: therefore, during the
time of these sayd six moneths of darknesse vnder the poles, the night is
destitute of the benefit of the Sunne and the sayd twilights onely for the
space of six weeks or thereabout. And yet neither this time of six weeks is
without remedy from heauen; for the Moone with her increased light hath
accesse at that time, and illuminateth the moneths lacking light euery one
of themselues seuerally halfe the course of that moneth, by whose benefit
