QQC 3 - Fleckenstein's Incarnate Word

Quote: "The physical mirroring of two images of embodiment from the Dialogue, images of birth and images of motherhood, as well as the three layers of embodiment—immersion in the world, immersion in God through prayer, and immersion in Christ—illustrates the ways in which Catherine, a virgin, became her own image event." 

Question: For Catherine, if these acts and ideals became "her own image event", then how did Catherine become an image event herself? Based on this idea, what does Fleckenstein define an image event and a "scopic regime" in the Middle Ages as?
