Naxos is a Greek island and the largest of the Cyclades. It was the centre of the archaic Cycladic culture. The island is famous as a source of emery, a rock rich in corundum, which until modern times was one of the best abrasives available.

The Cyclades are an island group in the Aegean Sea, southeast of mainland Greece and a former administrative prefecture of Greece. They are one of the island groups which constitute the Aegean archipelago. The name refers to the archipelago forming a circle around the sacred island of Delos. The largest island of the Cyclades is Naxos, however the most populated is Syros.
