The Greeks called it the "Aegean Pelagos" and the Italians referred to it as "Arcipelago" (principal sea), but English speakers now call it the Aegean Sea. Numerous islands dot its expanse, and 17th-century English speakers adopted a modified form of its Italian name for any sea with a similar scattering of islands. By the 19th century "archipelago" had come to refer to the groups of islands themselves, and now it is often used figuratively, as in, for example, "an archipelago of high rises."
