9The planet Venus, as soon as she escapes from the influence of the sun’s rays, runs through the space of one sign in forty days; and what she loses by stopping a long time in one sign, she makes up by her quick passage through others. She completes her circuit through the heavens in four hundred and eighty-five days; by which time she has returned to the sign from whence she set out.
9Venus, on becoming free from the hindrance of the sun’s rays, crosses the space of a sign in thirty days. Though she thus stays less than forty days in particular signs, she makes good the required amount by delaying in one sign when she comes to a pause. Therefore she completes her total revolution in heaven in four hundred and eighty-five days, and once more enters the sign from which she previously began to move.
