At least the later periods of Hallstatt art from the western zone are generally agreed to form the early period of Celtic art. Decoration is mostly geometric and linear, and best seen on fine metalwork finds from graves (see above). Styles differ, especially between the west and east, with more human figures and some narrative elements in the latter. Animals, with waterfowl a particular favourite, are often included as part of other objects, more often than humans, and in the west there is almost no narrative content such as scenes of combat depicted. These characteristics were continued into the succeeding La Tène style.
