Hilma af Klint was a Swedish painter born in 1862 who painted big, bold canvases suffused with rich, strange colors denoting masculine and feminine, the gush of life and the serenity of cosmic order. She found inspiration in unorthodox places, including the spirit realm. And she had a vision: that her work would one day be displayed in a spiral temple.

For decades after her death, her work was hidden away — at first by her request, and then because it couldn't find an audience. Now that it's on display in a building like the one she imagined, her work is a sensation that has invited a radical re-imagining of the history of abstract art. In 2019, Brooke walked through the exhibit with senior curator Tracey Bashkoff, who brought af Klint's work to the Guggenheim after discovering it in a catalogue.

Next, Brooke explores Spiritualism — a movement that shaped af Klint's life and work. Broadly defined as a religious movement based on the idea that the living can communicate with spirits dwelling in the afterlife — that we can talk to the dead — Spiritualism grew quickly. After all, the telegraph was allowing people to communicate across time and space; why not spiritual realms?

At the time, the ideal spirit medium was thought to be an adolescent girl, unencumbered by education and thoughts of her own. But a curious thing happened as women started speaking as spirit mediums: they became accustomed to speaking in public, and others became accustomed to hearing them. And on top of that, the spirits had some radically progressive ideas about individual self-sovereignty, abolition and women's rights. Brooke speaks with Ann Braude, director of the Women's Studies in Religion Program at Harvard Divinity School and author of Radical Spirits: Spiritualism and Women's Rights in Nineteenth-Century America, about this curious moment in American history, and how it helped bring women — and reformist ideas — into the public sphere.
