The lapis-Christ parallel was presumably the bridge by which the mystique of the Rose entered into alchemy. This is evident first of all from the use of ‘Rosarium’ or ‘Rosarius’ (rose-gardener) as a book title.
Jung establishes the Rosarium philosophorum as the primary alchemical text mediating between rose-mysticism and the lapis-Christ parallel, making ‘Rosarium’ a pivotal term in his alchemical hermeneutics.
