The name of the islands is first recorded by the ancient geographer Claudius Ptolemaeus (born AD 90, died AD 168), who called them Orcades. The old Gaelic name for the islands was Insi Orc which means the "Island of the Orcs". An orc is a young pig or boar. When the Norwegian Vikings arrived on the islands they interpreted the word orc to be orkn which is Old Norse for pinnipeds or common seal. The suffix ey means island. Thus the name became Orkneyjar which was shortened to Orkney in English.
