The author discusses the possible sources (illustrated bestiaries of the 13-14th centuries) in studies of animals by Leonardo da Vinci. In addition to specific works that the artist could have consulted in the ducal library of Pavie, the tradition of the international Gothic style, with its Arab components, is described as the source of inspiration of Leonardo da Vinci.
