Claviform signs: The signs called 'claviform' (key-shaped) are fairly abundant, specially in gallery B and in Room XI, but are doubtful if not indeed non-existent in Gallery A. Those of Room XI are the most characteristic and may be associated with horses. One of these can be considered as what Leroi-Gourhan calls a 'coupled sign',[1] made by uniting in the same ideomorph a line or bar (masculine) with a key-shape (feminine). The typology and chronology of these signs is very ample.
