The ancient Greek colonization of Cyrenaica in the 7th century BC began when settlers from the island of Thera (modern Santorini), on the recommendation of the Delphic oracle, founded a colony on the island of Platea, off the coast of North Africa. However, modern islands suitable for such a colony do not exist in these places. So the island of Platea had to be found. This story will be about the search and discovery of the island of Platea.
