 Hoddinott states that the twin spiral terminals, as on the bowl from Biia, would have been a natural development; either from a local single armlet type or from an Unetice spectacle pendant.The other opinion attributes the spiral motif to a northward spread of Mycenaean influence.It is argued that the spiral of the Neolithic period disappeared during the transitional period towards the Bronze Age, and even during the Early Bronze Age; therefore, starting from the Middle Bronze Age the spiral would occur because of a Mycenaean sway to the north of the Danube.
