Since the 20th century a multitude of scholars have studied the linguistic, cultural and racial background of the Sarakatsani. Among these, Danish scholar Carsten Høeg, who travelled twice to Greece between 1920 and 1925 and studied the dialect and narrations of the Sarakatsani, is arguably the most influential. He found no traces of foreign elements in the Sarakatsani dialect and no traces of sedentism in their material culture. Furthermore, he looked for examples of nomadism in classical Greece, similar to that of the Sarakatsani. He visited the Sarakatsani of Epirus and mentioned other groups with no fixed villages in several other parts of Greece as well.
