Panchaia (island)

Panchaia is an island mentioned in historic literature whose location has never been determined.
It was first mentioned by ancient Greek philosopher Euhemerus in the late 4th century BC. Euhemerus describes this place as home to a utopian society made up of several different ethnic tribes that had a collective economy. He described his trip there in his major work Sacred History, only fragments of which survive. The later Greek historian Diodorus Siculus and 4th century AD Christian writer Eusebius of Caesarea preserved fragments of his writings. The surviving fragments describe Panchaia as a rational island paradise located in the Indian Ocean. Euhemerus went there by traveling through the Red Sea and around the Arabian Peninsula. In Panchaia's temple of Zeus Triphylius, he found a register of the births and deaths of the gods, proving they were merely historical figures.
Panchaia is also mentioned by Lygdamus, one of the Tibullan elegists, as a rich place from which he will hope for gifts to his grave.
Virgil described Panchaia as "incense bearing, rich with sands".
Possible locations include Socotra and Bahrain.
