reindeer, elk, bears, birds, seals, whales, and fish (especially salmon and halibut), all of which were vital to the way of life of the coastal peoples. The carvings at Alta in Finnmark, the largest in Scandinavia, were made at sea level continuously from 4,200 to 500 BC and mark the progression of the land as it rose from the sea after the last ice age (Rock carvings at Alta).
Bronze Age
Between 3000 and 2500 BC new settlers (Corded Ware culture) arrived in eastern Norway. They were Indo-European farmers who grew grain and kept cows and sheep. The hunting-fishing population of the west coast was also gradually replaced by farmers, though hunting and fishing remained useful secondary means of livelihood.
From about 1500 BC bronze was gradually introduced, but the use of stone implements continued; Norway had few riches to barter for bronze goods, and the few finds consist mostly of elaborate weapons and brooches that only chieftains could afford. Huge burial cairns built close to the sea as far north as Harstad and also inland in the south are characteristic of this period. The motifs of the rock carvings differ from those typical of the Stone Age. Representations of the Sun, animals, trees, weapons, ships, and people are all strongly stylized, probably as fertility symbols connected with the religious ideas of the period.
Iron Age
Little has been found dating from the early Iron Age (the last 500 years BC). The dead were cremated, and their graves contain few burial goods. During the first four centuries AD the people of Norway were in contact with Roman-occupied Gaul. About 70 Roman bronze cauldrons, often used as burial urns, have been found. Contact with the civilized countries farther south brought a knowledge of runes; the oldest known Norwegian runic inscription dates from the 3rd century. At this time the amount of settled area in the country increased, a development that can be traced by coordinated studies
