The Picts were a group of Celtic-speaking peoples who lived in what is now northern and eastern Scotland (north of the Forth) during Late Antiquity and the Early Middle Ages. Where they lived and what their culture was like can be inferred from early medieval texts and Pictish stones. Their Latin name, "Picti", appears in written records from the 3rd to the 10th century. Early medieval sources report the existence of a distinct Pictish language, which today is believed to have been an Insular Celtic language, closely related to the Brittonic spoken by the Britons who lived to the south.
