Bronze Age Ireland

Metallurgy arrived in Ireland with new people, generally known as the Bell Beaker People, from their characteristic pottery, in the shape of an inverted bell.This was quite different from the finely made, round-bottomed pottery of the Neolithic. It is found, for example, at Ross Island, and associated with copper-mining there. 

The Bronze Age began once copper was alloyed with tin to produce true Bronze artifacts, and this took place around 2000 BC, when some Ballybeg flat axes and associated metalwork were produced. The period preceding this, in which Lough Ravel and most Ballybeg axes were produced, and which is known as the Copper Age or Chalcolithic, commenced about 2500 BC.

Bronze was used for the manufacture of both weapons and tools. Swords, axes, daggers, hatchets, halberds, awls, drinking utensils and horn-shaped trumpets are just some of the items that have been unearthed at Bronze Age sites. Irish craftsmen became particularly noted for the horn-shaped trumpet, which was made by the cire perdue, or lost wax, process.

Copper used in the manufacture of bronze was mined in Ireland, chiefly in the southwest of the country, while the tin was imported from Cornwall in Britain. The earliest known copper mine in these islands was located at Ross Island, at the Lakes of Killarney in County Kerry; mining and metalworking took place there between 2400 and 1800 BC. Another of Europe’s best-preserved copper mines has been discovered at Mount Gabriel in Cork^. Mines in Cork and Kerry are believed to have produced as much as 370 tonnes of copper during the Bronze Age. As only about 0.2% of this can be accounted for in excavated bronze artifacts, it is surmised that Ireland was a major exporter of copper during this period.

Ireland was also rich in native gold, and the Bronze Age saw the first extensive working of this precious metal by Irish craftsmen. More Bronze Age gold hoards have been discovered in Ireland than anywhere else in Europe. Irish gold ornaments have been found as far afield as Germany and Scandinavia. In the early stages of the Bronze Age these ornaments consisted of rather simple crescents and disks of thin gold sheet. Later the familiar Irish torque made its appearance; this was a collar consisting of a bar or ribbon of metal, twisted into a screw and then bent into a loop. Gold earrings, sun disks and lunulas (crescent “moon disks” worn around the neck) were also made in Ireland during the Bronze Age.

Smaller wedge tombs continued to be built throughout the Bronze Age, and while the previous tradition of large scale monument building was much reduced, existing earlier megalithic monuments continued in use in the form of secondary insertions of funerary and ritual artifacts. Towards the end of the Bronze Age the single-grave cist made its appearance. This consisted of a small rectangular stone chest, covered with a stone slab and buried a short distance below the surface. Numerous stone circles were also erected at this time, chiefly in Ulster and Munster.

During the Bronze Age, the climate of Ireland deteriorated and extensive deforestation took place. The population of Ireland at the end of the Bronze Age was probably in excess of 100,000, and may have been as high as 200,000. In Ireland the Bronze Age lasted until c. 500BC, later than the Continent and also Britain.
