Sweden is first described in a written source in Germania by Tacitus in 98 AD. In Germania 44 and 45 he mentions the Swedes 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. Which kings
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 AD, 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.
