Answer the following question: What had a return to prominence in the Anglo-Saxon period?  Answer the above question based on the context below:  The boar was an important symbol in prehistoric Europe, where, according to the archaeologist Jennifer Foster, it was "venerated, eulogised, hunted and eaten ... for millennia, until its virtual extinction in recent historical time." Anglo-Saxon boar symbols follow a thousand years of similar iconography, coming after La Tène examples in the fourth century BC, Gaulish specimens three centuries later, and Roman boars in the fourth century AD. They likely represent a fused tradition of European and Mediterranean cultures. The boar is said to have been sacred to a mother goddess figure among linguistically Celtic communities in Iron Age Europe, while the Roman historian Tacitus, writing around the first century AD, suggested that the Baltic Aesti wore boar symbols in battle to invoke her protection. Boar-crested helmets are depicted on the turn-of-the-millennium Gundestrup cauldron, discovered in Denmark, and on a Torslunda plate from Sweden, made some five hundred years later. Though the Romans also included the boar in their stable of symbols—four legions, including the twentieth, adopted it as their emblem—it was only one among many. The boar nonetheless persisted in continental Germanic tradition during the nearly 400 years of Roman rule in Britain, such as in association with the Scandinavian gods Freyja and Freyr. Its return to prominence in the Anglo-Saxon period, as represented by the boars from Benty Grange, Wollaston, Guilden Morden, and Horncastle, may therefore suggest the post-Roman reintroduction of a Germanic tradition from Europe, rather than the continuation of a tradition in Britain through 400 years of Roman rule. Whatever its precise symbolism, the Anglo-Saxon boar appears to have been associated with protection; the Beowulf poet makes this clear, writing that boar symbols on helmets kept watch over the warriors wearing them.
