Sweden's prehistory begins in the Allerod oscillation, a warm period around 12,000 BC, with Late Palaeolithic reindeer-hunting camps of the Bromme culture at the edge of the ice in what is now the country's southernmost province, Scania. This period was characterized by small bands of hunter-gatherer-fishers using flint technology.
Sweden is first described in a written source in Germania by Tacitus in 98 CE. In Germania 44 and 45 he mentions the Swedes (Suiones) as a powerful tribe (distinguished not merely for their arms and men, but for their powerful fleets) with ships that had a prow at each end (longships). Which kings (kuningaz) ruled these Suiones is unknown, but Norse mythology presents a long line of legendary and semi-legendary kings going back to the last centuries BC. As for literacy in Sweden itself, the runic script was in use among the south Scandinavian elite by at least the 2nd century CE, but all that has come down to the present from the Roman Period is curt inscriptions on artefacts, mainly of male names, demonstrating that the people of south Scandinavia spoke Proto-Norse at the time, a language ancestral to Swedish and other North Germanic languages.
In the 6th century, Jordanes names two tribes living in Scandza, both of which are now considered to be synonymous with the Swedes: the Suetidi and Suehans. Suetidi is considered to be the Latin form of sweden, the Old Norse name for the Swedes. Jordanes describes the Suetidi and Dani as being of the same stock and the tallest of people. He later mentions other Scandinavian tribes as being of a same stature. The Suehans were known to the Roman world as suppliers of black fox skins and, according to Jordanes, had very fine horses, similar to those of the Thyringi of Germania (alia vero gens ibi moratur Suehans, quae velud Thyringi equis utuntur eximiis). The Icelandic historian Snorri Sturluson also wrote that the Swedish king Adils (Eadgils) had the finest horses of his day.
