There are two myths about early medieval Ireland. One is that it was an ignorant, isolated place. The other is that without Ireland, civilisation would have been lost.
Pollen evidence suggests a growing population in the Ireland of the third and fourth centuries, with agricultural expansion and forest clearance taking place after a previous decline. The landscape was dominated by pastureland, intermingled with scrubby woodland and mixed farming, with few large areas of forest1.
This was a rural society, broken up into túatha and kingdoms. However it was not isolated from the world. Tacitus tells us in the first century AD Roman traders knew the major routes to, and harbours in, Ireland. Imports included wine and fine cloth. There were also Roman-Irish contacts via Romano-British slaves in Ireland and Irish settlements in Wales2. In Wales as well as in Ireland itself we find evidence of the first Irish writing, Ogham.
