Bonaventure, on Dan 8:16

“And I heard the voice of a man between Ulai: and he called, and said: Gabriel, make this man to understand the vision.”

“"Now it came to pass, when I, Daniel, saw the vision and sought understanding: behold, there stood before me as it were the appearance of a man; and he cried out and said: Gabriel, make this one understand the vision." This illumination is aided through the Angels. These visions descended from the Father of lights, and the Angel aids the intellect of Daniel, so that he might grasp the light of God and through it understand. It is true that man is instructed ministerially and supportively through an Angel, as was evident in Daniel: but effectively God alone has power over the rational soul itself, because it is immediately formed by God. The Angel illumines in the way that one who opens a window is said to illuminate a house.”
