Gregory the Great, on 1Sam 1:20

“And it came to pass when the time was come about, Anna conceived and bore a son, and called his name Samuel: because she had asked him of the Lord.”

“(Moral Exposition) But what does it mean that Anna conceives and gives birth after the cycle of days, except that contemplation, once elevated to the beauty of the Creator, does not receive the joy of perfect devotion? Therefore she is said to have conceived and given birth after the cycle of days, because when contemplation is habitually seized up to heavenly things, it receives the gift of desired fruitfulness in the vision of heavenly light. For the cycle of days is the infusion of divine light. This is indeed encompassed by many days in its circuit, while it illuminates the mind with its single brightness, yet it gradually introduces the rays of its splendor to the mind through alternating manifestations of its dispensation, until it comprehends a more perfect joy from a fuller manifestation. Or certainly Anna conceives after the cycle of days, because indeed as long as the rawness of contemplation shakes the mind's sharp gaze in the whirl of mutability, the mind itself does not rise to perceive the full joy of inner majesty. For days pass as if in a certain circle, when the mind of the beginner elevates itself to the height of contemplation, but the ray of light, though glimpsed, scarcely keeps the mind, still wavering and wandering, fixed in its light. Therefore she conceives after the cycle of days, because first the soul is led from the dizziness of its change into the strength of standing firm, and when it has learned from practice to stand fixed in contemplation, it grasps the joy of perfect devotion in the fruit of its fruitfulness. This conception it also brings forth when it makes known to neighbors the glory of heavenly majesty.”
