It seems highly probable, and almost certain, that Leonardo was in search of a work by Ramon Lull, and that he was still looking for it when he wrote the Leicester manuscript or that he wished to re-examine it. The reference would not be out of place in this manuscript. In fact, in the congeries of the questions forming the ars lulliana, or if we wish to use Leonardo’s term for it, the ramondina, are those which Lull calls elementales or elementativae, and among them some which Leonardo tried to resolve on more than one occasion, and which fell more specifically within the subject area he was dealing with.
