The Nereid Monument is a sculptured tomb from Xanthos in Lycia (then part of the Achaemenid Persian Empire), close to present-day Fethiye in Mugla Province, Turkey. It took the form of a Greek temple on top of a base decorated with sculpted friezes, and is thought to have been built in the early fourth century BC (circa 390 BC) as a tomb for Arbinas (Lycian: Erbbina, or Erbinna), the Xanthian dynast who ruled western Lycia under the Achaemenid Empire. The tomb is thought to have stood until the Byzantine era before falling into ruin. The ruins were rediscovered by British traveller Charles Fellows in the early 1840s. Fellows had them shipped to the British Museum, where some of them have been reconstructed to show what the east façade of the monument would have looked like. According to Melanie Michailidis, though bearing a "Greek appearance", the Nereid Monument, the Harpy Tomb and the Tomb of Payava were built in accordance with main Zoroastrian criteria "by being composed of thick stone, raised on plinths off the ground, and having single windowless chambers". The Nereid Monument was the main inspiration for the famous Mausoleum at Halicarnassus. Tombs at Xanthos Xanthos, also called Xanthus, was a chief city state of the Lycians, an indigenous people of southwestern Anatolia (present-day Turkey). Many of the tombs at Xanthos are pillar tombs, formed of a stone burial chamber on top of a large stone pillar. The body would be placed in the top of the stone structure, elevating it above the landscape. The tombs are for men who ruled in a Lycian dynasty from the mid-6th century to the mid-4th century BCE and help to show the continuity of their power in the region. Not only do the tombs serve as a form of monumentalization to preserve the memory of the rulers, but they also reveal the adoption of Greek style of decoration. Xanthos was chief city state governed by a king, who was under an Achaemenid Empire governor. The continuity of the dynastic rule in Xanthos was shown through a tradition of building pillar tombs.
