The term Libyan Sea (Mare Libycum) was used by ancient geographers to describe the part of the Mediterranean Sea south of Crete, between Cyrene and Alexandria. It referred to the region of "Libya" in antiquity, which encompassed much of North Africa west of the Nile River. The name "Libya" (Greek: Λιβύη, Libyē) originally referred to a broader area than the modern country of Libya.[4]
In ancient times, "Libya" described the lands and peoples of North Africa, such as the Libu and Meshwesh tribes, as recorded by Greek and Roman sources.[5] The modern usage of "Libyan Sea" continues this tradition and is commonly found in maps and travel literature.[6]
