Her incredibly beautiful island Apple, which is located in the Aegean Sea and belongs to the Cyclades island complex, inhabited since prehistoric times. It is horseshoe shaped and, in addition to its long and rich history, it is also known for its two dormant volcanoes. Their existence naturally led to the formation of obsidian, which is a black colored volcanic glass. Thanks to this naturally produced glass, the population of Milos flourished as people quickly realized that obsidian could be used to make tools or even weapons. During the Bronze Age, obsidian became less and less popular as copper became more preferred.
