Pardon the pedantry but there are no Neolithic -BA labyrinths in the British or Irish RA corpus ,or in the megalithic art from Iberian /Franco passage graves ,that I know of .There is a definite similarity due to central cups being surrounded by rings ,penannulars,spirals ,arcs etc but none have the rigidity of that design . The Saward article was right to use the the term labyrinthine .There are a bunch of labyrinths in Russia that he didn't mention , thatsome have considered to be neolithic but with the usual problems regarding dating impossible to prove and unlikely .
