Very little of Katherine’s alchemical work has survived; however, Kitchin-Physick is a book that she wrote containing medical recipes (Hunter, 1997b). Another book of general remedies residing in the Wellcome Institute Library is also attributed to Katherine. Albeit frustrating for scholars but intriguing for conspiracy theorists, Katherine’s letters are missing, lost, or destroyed but some historians believe they exist somewhere (Hunter 2004).
The notion of Katherine’s connection to alchemy is quite logical given her living circumstances. It is known she worked with medicinal herbs and her brother practiced alchemy. Reading correspondence between Katherine and Robert demonstrates the ease with which they conversed on scientific matters. Their topics of discourse included politics, theology, and philosophy. Robert often refers to Katherine’s previous letters in which she has raised these issues indicating that the siblings entertained a lively exchange of ideas. For example, in a letter dates March 6, 1647, Robert writes about one of his furnaces falling apart upon being moved which was a disaster for his experiments.
Katherine Boyle Jones was both pious as well as tolerant regarding religious issues. Like her best friends, Dorothy Moore and John Dury, her inclination was toward millenarianism, a belief regarding Christ’s return according to the prophecy described in Revelation. People believed that just as God created the earth and was incarnated as Jesus on earth, that the last days of judgment would also take place, not in heaven but on earth (Oliver, 1978).
The millenarianism practiced by Dorothy Moore and Katherine Boyle Jones brought them into contact with the study of writings from the Kabbalah as well as those of alchemical and/or occult focus. Jacob (1998) argues that there was also a clear association between millenarians and devotees of the alchemist/medical doctor, Paracelsus. He further contends that part of the context of the uprising against Charles I was that the monarchy/government monopolized industry, the law, and medicine. Upon abolishing the monarchy, more common medical practitioners who followed Paracelsus, such as surgeons and apothecaries, who were also unable to be accepted into the Royal College of Physicians, could emerge in a stronger position. For example, Samuel Hartlib, a millenarian, was also involved with translating Paracelsus’ work into English. How did it equate with millenarianism? Alchemists commonly studied each of these fields but it is interesting to explore the theological link.
