the ancient royal residence of the kings of Persia, built by Darius Hystaspis, according to Pliny; though he probably only restored it, being a very ancient city, founded by Tithonus father of Memnon. It was in compass 120 stadia, of an oblong quadrangular form, with a citadel called Memnonium. In scripture it is called Sufan, the royal citadel, from the great number of lilies growing in that district (Athenaeus); situated on the river Uhli, or Eulaeus (Daniel): and the Spaniards call at this day a lily asyena (Pinedo). Sufa was the winter, as Ecbatana was the summer, residence of the kings of Persia, (Xenophon, Strabo, Plutarch). Here the kings kept their treasure, (Herodotus). Now called Tyfer.
