Original sentence: It is only in the Hellenistic period that stray finds become available as far north as Macedonia (see Pella curse tablet).The  extent of the dialect's distribution towards the north is unknown for lack of epigraphic evidence
Edited sentence: Local epigraphical evidence is restricted to the decrees of the Epirote League and the Pella curse tablet  (both in early 4th century BC), as well to the Doric eponym Machatas first attested in Macedonia (early 5th century BC).Regarding the dialect of the Epirote League, it was not Corinthian Doric, even the alphabet was not Corinthian; it was probably North-West Doric, as some recorded inquiries at Dodona seem to show.The dialect's distribution towards the north extends to the Megarian colony of Byzantium and the Corinthian colonies of Potidaea,Epidamnos, Apollonia and Ambracia
