Chalcis (ˈkælsᵻs; Ancient Greek & Katharevousa: Χαλκίς, ), also called Chalkida or Halkida (Modern Greek: Χαλκίδα, xalˈciða), is the chief town of the island of Euboea or Evia in Greece, situated on the Euripus Strait at its narrowest point. The name is preserved from antiquity and is derived from the Greek χαλκός (copper, bronze), though there is no trace of any mines in the area. In the Late Middle Ages, it was known as Negropont(e), an Italian name that has also been applied to the entire island of Euboea.
The earliest recorded mention of Chalcis is in the Iliad, where it is mentioned in the same line as its rival Eretria. It is also documented that the ships set for the Trojan War gathered at Aulis, the south bank of the strait near the city. Chamber tombs at Trypa and Vromousa dated to the Mycenaean period were excavated by Papavasiliou in 1910. In the 8th and 7th centuries BC, colonists from Chalcis founded thirty townships on the peninsula of Chalcidice and several important cities in Magna Graecia and Sicily, such as Naxos, Rhegion, Zankle and Cumae. Its mineral produces, metal-work, purple, and pottery not only found markets among these settlements but were distributed over the Mediterranean in the ships of Corinth and Samos. The development of the city leads consequently to the increase of the population and finally to the colonization with the establishment of many important cities in the West, but also in the Greek area. The first recorded settlement in the West, which paved the way for the 2nd Greek colonization, is Pithecusae on the island of Ischia, in front of Naples, from Chalcidians and Eretrians around 770 BC. The etymology of the toponym "Pithikousa" comes from the pithos (pitharia) that the first settlers had with them to transport their products. Because of the first Chalcidian settlers, the Romans initially called all Greeks "Chalcidians", as they were the first Greeks they came into contact with.A few years later, the Chalcidian Antimnestos founds Rigio in 730-720 BC.
