The most popular hypothesis on the origin of Griko is the one by
Gerhard Rohlfs and
Georgios Hatzidakis, that Griko's roots go as far back in history as the time of the
ancient Greek colonies in
Southern Italy and
Sicily in the eighth century BC. The Southern Italian dialect is thus considered to be the last living trace of the Greek elements that once formed
Magna Graecia. There are, however, competing hypotheses according to which Griko may have preserved some
Doric elements, but its structure is otherwise mostly based on
Koine Greek, like almost all other Modern Greek dialects. Thus, Griko should rather be described as a Doric-influenced descendant of
Medieval Greek spoken by those who fled the
Byzantine Empire to Italy to escape the
Turks. The idea of Southern Italy's Greek dialects being historically derived from Medieval Greek was proposed for the first time in the 19th century by Giuseppe Morosi. == Geographic distribution ==
