You can see this happening all during Through a Glass Darkly, which tells the story of a father, his daughter and son, and the daughter's husband, isolated on a remote Swedish island for a summer vacation. They're living in a run-down cottage. The opening scenes are deliberately banal, as they emerge from a dip in the sea and debate about who will fix dinner and who will put out the nets. But deeper currents emerge. We hear about the "sickness" of the daughter, Karin (Harriet Andersson). It is never named, but is clearly schizophrenia. She has been treated and is going through a period of recovery. Her husband, Martin (Max von Sydow), loves her but feels powerless to help her. Her brother, nicknamed Minus (Lars Passgard), is balanced at the entry to adolescent sexuality, and is very aware of the physical reality of his sister. The father, David (Gunnar Bjornstrand), is an author, highly regarded, who has just returned from a stay in Switzerland. He is cool and distant.
During the course of the first evening, the children will put on a play for their father, which has as its subject the impotence of art. It can be seen as a veiled attack on his novels. Later, Minus asks Karin if she noticed how offended their father was. Not particularly. The characters separate, the married couple together, the other two in their rooms. It is a long Swedish summer night; when darkness falls, the sun is already rising again.
This perpetual daylight has an eerie effect. Everything that happens is like a waking dream. Karin rises up from her bed and climbs the stairs to a shabby upper floor, and enters a room. She seems almost in a trance. She clings to the wall and traces out figures in the wallpaper. When she is found, she at first seems disturbed, but then cheers up and acts normally. Later she will tell her brother that voices called to her, that the wallpaper opened a door, that those on the other side were waiting for something, and that she thinks it might have been God. Still later, famously, she says she saw God, and he was a spider.
Left alone in her father's room, she reads his journal, where he confesses his obsession with his daughter's illness, notes that it is "incurable," and confesses he is interested in how he could use it in his work. This deeply upsets her. Earlier she had teased her brother after catching him looking at a pinup magazine. He had accused her of wearing seductive clothes. Now her brother goes seeking her on the beach and finds her huddled inside the wreck of a burned-out boat. There is an extraordinary scene, making great use of meticulously lighted two-shots, emphasizing their closeness and their separation. At the end of the scene, there is an implication that an act of incest occurs, although Bergman is deliberately obscure.
There have been other fraught scenes-between Karin and Martin, for example, who she has drawn apart from physically. And between Martin and David. Finally all comes down to Karin having a relapse. An ambulance is called; it is a helicopter, which apparently she experiences as a spider descending from the sky.
You can freeze almost any frame of this film and be looking at a striking still photograph. Nothing is done casually. Verticals are employed to partition characters into a limited part of the screen. Diagonals indicate discord. The characters move into and out of view around the cottage as if in a play. The visual orchestration underlines the disturbance of Karin's mental illness, and the no smaller turmoil within the minds of the others.
I was impressed time and again by how painstakingly the film had been made. Nykvist's lighting is essentially another character. How he sees, how he shades, how he conceals, all sum up into how we are to feel about the characters. The same film photographed by another cinematographer might seem shallow, even silly. Certainly Bergman attracted his share of parody. But this film, shot this way, surprises us by how much power it builds.
Peter Cowie, an expert on Bergman, appears in a short subject on the Criterion DVD and says the trilogy was Bergman's way of unloading the "baggage" of his religious upbringing; his father was a strict Lutheran minister. Bergman still has a great deal of that upbringing left over for his other films, which often deal with mortality, guilt, sin, God, and demons. But in these three, there is a focus almost painfully intense.
Through a Glass Darkly would be followed by Winter Light, about a minister who despairs of God's silence, and by The Silence, about two sisters and the child of one, stranded in a strange town and haunted by old hatreds and wounds. Long stretches of that film are silent, or at least lacking in dialogue, as the boy prowls a hotel's corridors, making fantasies of his own to displace the disturbance being trapped between the two sisters. In all of these films, we're struck by Bergman's deep concern that humans see the world as through a glass, darkly, and are unable to perceive its meaning.
