the tools for what some interpret as a form of divination. However, as the tale doesn't explain how the sticks are handled or interpreted, this theory is open to interpretation. A divination method invented by neopagans involves casting sticks upon a cloth marked out with a pattern, such as Finn's Window, and interpreting the patterns. The meanings assigned in these modern methods are usually based on the tree ogham, with each letter associated with a tree or plant, and meanings derived from these associations. While some use folklore for the meanings, Robert Graves' book The White Goddess continues to be a major influence on these methods and beliefs.
