They settled in their new lands and became farmers and fishermen. Archaeological evidence shows no tradition of monumental artwork, such as architecture or large sculpture in permanent materials, but a preference instead for “mobile” art for personal display, usually also with a practical function, such as weapons, horse harness, tools, and jewelry which fastened clothes. The surviving art of the Germanic peoples is almost entirely personal adornment, portable, and before conversion to Christianity was buried with its owner. Much art in organic materials has no doubt not survived.
