In William Butler Yeats and Lady Augusta Gregory’s collaborative play The Pot of Broth (1904), ostensibly a light farce, a beggar visits a couple and convinces them that a stone he carries is magical and can be boiled to make broth. As he demonstrates this “magic,” there is a crucial passage in which the tramp asks for herbs. By reading this passage alongside Gregory’s other writings on herbs, and in the light of her association with the healer Bridget Ruane, we can understand the tramp’s role in the play better, and the role of non-elite women like Ruane in the creation of the culture of the Revival. Gregory’s “Herb-Healing” chapter in Poets and Dreamers: Studies and Translations from the Irish (1902) and the “Herbs, Charms, and Wise Women” section in the second series of Visions and Beliefs in the West of Ireland (1920) throw light on The Pot of Broth. Many of the herbs that Gregory lists and describes in these folklore collections are repurposed as literary ingredients that she and Yeats mix into The Pot of Broth, as well as other plays, where they create a symbolic language of healing herbs.
