Pallantium or Pallantion, more rarely Palantium or Palantion (Παλάντιον), was one of the most ancient towns of Arcadia, in the district Maenalia, said to have been founded by Pallas, a son of Lycaon. It was situated west of Tegea, in a small plain called the Pallantic plain which was separated from the territory of Tegea by a dyke. It was from this town that Evander of Pallene was said to have led colonists to the banks of the river Tiber, and from it the Palatino or Palatine Hill in Rome was reputed to have derived its name.
