15. The sun[170] goes forth through this fourth gate, and sets in it,
and turns to the fifth gate during thirty days; after which it proceeds
from, and sets in, the fifth gate.
16. Then the day becomes lengthened by a second portion, so that it is
eleven parts: while the night becomes shortened, and is only seven
parts.
17. The sun _now_ returns to the east, entering into the sixth gate, and
rising and setting in the sixth gate thirty-one days, on account of its
signs.
18. At that period the day is longer than the night, being twice _as
long as_ the night; and becomes twelve parts;
19. But the night is shortened, and becomes six parts. Then the sun
rises up, that the day may be shortened, and the night lengthened.
20. And the sun returns towards the east, entering into the sixth gate,
where it rises and sets for thirty days.
21. When that period is completed, the day becomes shortened precisely
one part, so that it is eleven parts, while the night is seven parts.
22. Then the sun goes from the west, from that sixth gate, and proceeds
eastwards, rising in the fifth gate for thirty days, and setting again
westwards in the fifth gate of the west.
23. At that period the day becomes shortened two parts; and is ten
parts, while the night is eight parts.
24. Then the sun goes from the fifth gate, as it sets in the fifth gate
of the west; and rises in the fourth gate for thirty-one days, on
account of its signs, setting in the west.
25. At that period the day is made equal with the night; and, being
equal with it, the night becomes nine parts, and the day nine parts.
26. Then the sun goes from that gate, as it sets in the west; and
returning to the east proceeds by the third gate for thirty days,
setting in the west at the third gate.
27. At that period the night is lengthened from the day during thirty
mornings, and the day is curtailed from the day during thirty days; the
night being ten parts precisely, and the day eight parts.
28. The sun now goes from the third gate, as it sets in the third gate
in the west; but returning to the east, it proceeds by the second gate
of the east for thirty days.
29. In like manner also it sets in the second gate in the west of
heaven.
