Note 1 — CANTO II.
Charles Eliot Norton translation
Purgatory and Jerusalem are antipodal, and in one direction the Ganges or India was arbitrarily assumed to be their common horizon. The night is here taken as the point of the Heavens opposite the sun, and the sun being in Aries, the night is in Libra. When night exceeds, that is, at the autumnal equinox, when the night becomes longer than the day, the Scales may be said to drop from her hand, since the sun enters Libra.
