Thera is the ancient name for both the island of Santorini in the Greek Cyclades and the name of the volcano which famously erupted on the island in the middle Bronze Age. The 17th century BCE eruption covered Akrotiri, the most important settlement, in a layer of pumice and volcanic ash, thereby perfectly preserving the Bronze Age town.
