Prior to then the most credible and respected source, Tacitus in Germania Chapter 44 described the Suiones, who were divided into civitates (kingdoms?) along the coast of Scandinavia and were unusual in owning fleets of a special type of ship. These were pointed on both ends and were driven by banks of oars that could be rearranged or shipped for river passage. They did not depend on sail (so Tacitus says) but other than that they do not differ from Viking ships. These civitates went all the way around Scandinavia to the Arctic, or at least to regions of very long days, where they stopped.
