The Sitones were a Germanic people living somewhere in Northern Europe in the 1st century CE. They are only mentioned by Cornelius Tacitus in 97 CE in Germania. Tacitus considered them similar to Suiones (ancestors of modern Swedes):
Speculations on the Sitones' background are numerous. According to one theory, the name is a partial misunderstanding of Sigtuna, one of the central locations in the Swedish kingdom, which much later had a Latin spelling Situne. Related to this may be a memory of a period in which the Swedes were ruled by a queen as described in the Disas saga.
Another view is that the "queen" of the Sitones derives by linguistic confusion with an Old Norse word for "woman" from the name of the Kvens or Quains.
As pointed out by Kemp Malone, Tacitus' characterization of both the Suiones and the Sitones is "a work of art, not a piece of historical research", with the Sitones' submission to a woman as the logical culminating degeneracy after the Suiones' total submission to their king and surrendering of their weapons to a slave.
