Euboea, or Negropont or Negroponte (Modern Greek: Εύβοια Évia, Ancient Greek Εὔβοια Eúboia; see also List of traditional Greek place names), is the second largest of the Greek Aegean Islands and the second largest Greek island overall in area (1609 sq. miles) and population (after Crete). It is separated from the mainland of Greece by the Euboic Sea. In general outline it is long and narrow; it is about 150 km (90 miles) long, and varies in breadth from 50 km (30 miles) to 6 km (4 mi). Its general direction is from N.W. to S.E., and it is traversed throughout its length by a mountain range, which forms part of the chain that bounds Thessaly on the east, and is continued south of Euboea in the lofty islands of Andros, Tenos, and Mykonos.
