Note 2 — CANTO IX.
Charles Eliot Norton translation
The conical shadow of the earth ended, according to Ptolemy, at the heaven of Venus. Philalethes suggests that there may be here an allegorical meaning, the shadow of the earth being shown in feebleness of will, worldly ambition, and inordinate love, which have allotted the souls who appear in these first heavens to the lowest grades in Paradise.
