This book describes a trajectory of formalized apprenticeship in a Mande divination system. This apprecticeship demonstrates, in contrast to what theories predict, that formalized arithmetic education can exist in a society that has not developed a system of mathematics, that has a low level of literacy, and in which writing is mostly a technology used for the reproduction of religious texts (and not for the organization of the society). At the same time, this book describes the hitherto never noticed divination system of the Mande Mountains, which is a system with twenty-two "houses". The numerology of this system may offer new perspectives on "classical" Mande texts of creation myths.
