Eretria

Eretria (ĕrē`trēə), ancient city of Greece, in Euboea (now Évvoia), SE of Chalcis (now Khalkís), its rival. In the 7th and 6th cent. B.C., Eretria sent out many colonists to islands and coasts of the N Aegean. It supported (499 B.C.) the Ionian cities in the revolt against Persian control. In retaliation Darius I destroyed (490 B.C.) the city. Athens planted (c.445 B.C.) a colony there, which revolted in 411 with the rest of Euboea. Much later, after the second Delian League had been created, Eretria again revolted (349 B.C.). Excavations have uncovered the city walls, temple of Apollo, theater, and some public buildings.

Eretria

Ancient Greek town on the island of Euboea. Jointly with its neighbour Chalkís, it founded Cumae in Italy (c. 750 BC), the first of the Greek colonies in the west. Subsequent rivalry with Chalkís culminated in war, and by the Classical period Chalkís was the leading city of Euboea. In 499–498 BC Eretrian triremes sailed to support the Ionian revolt against Persia, for which act Darius I destroyed the city (490 BC) and deported the population. It was rebuilt, but under Macedonian and Roman rule it became insignificant. There are extensive ruins at the site.

Eretria 

(Nea Psara), an ancient Greek city on the southwestern coast of the island of Euboea. Having reached a high level of development in the eighth and seventh centuries B.C., Eretria founded colonies in Chalcidice, southern Italy, and Sicily. It was destroyed by the Persians in 490 B.C. for supporting the Ionian revolt, and its inhabitants were sold into slavery. After being rebuilt in 480 B.C. with the help of Athens, it joined the Delian League. After Greece was conquered by Rome in 146 B.C, Eretria was made part of the province of Macedonia.
