When I was around 15, he showed me a video of their first encounter with her, and to this day I cannot get the image of the pure terror on her face out of my mind. She had multiple visitors before, but something about this visit scared her so much that she hid inside for hours.
It turned out that this was the first visit where someone in the crew had brought video equipment (one of those big shoulder-mounted VHS cameras), and Agafia would later tell my grandfather that she thought this thing would 'steal her soul.' She wasn't shocked in amazement at the new technology, this was pure fear.
Reminds me of one of the early silent film The Arrival of a Train at La Ciotat Station [1], which allegedly was so realistic that people ran out of the movie theater screaming.
