What is Delos in Greek mythology?

In Greek mythology, Delos is a sacred island in the Aegean Sea. It is said that the god Apollo and his sister, the goddess Artemis, were born on Delos. As a result, Delos was considered a sacred place and was never inhabited. Instead, it was used as a sanctuary where people could come to worship Apollo and Artemis. Delos was also the home of the oracle of Apollo, which was consulted by people from all over the Greek world.
