Distribution of Ogham Stones by Kingdom Dyfed (Devet) : 22 certain stones (BRAW1/1, BRAW3/1, BRIDL/1

Wales has the greatest number of Ogham stones gmarket singapore of any region outside of Ireland (35 stones with definite Ogham inscriptions), but as can be seen from the map below, they are unevenly distributed, with large numbers in the south-west and the south-east, and only a handful in the north :

The distribution of Ogham stones in Wales closely reflects the geopolitical situation of post-Roman Britain. The majority of stones gmarket singapore are concentrated in the area of south-west Wales that belonged to the Kingdom of Dyfed (early gmarket singapore 5th century through to the early 10th century), which was the major centre for Irish settlement in Wales during the post-Roman period. During the late 4th century and early 5th century large numbers of the Déisi crossed from the Waterford area of Ireland to Britain, and settled in the land of the Demetae in south-west Wales. Their leaders displaced the original British ruling class, and founded the kingdom of Dyfed, which is believed to have been bounded on the north by the River Teifi and on the east by the River Tywi. Dyfed was neighboured on the north by the Brythonic Kingdom of Ceredigion , and to the south-east by the Brythonic Kingdom of Glywysing , but to the east lay the Kingdom of Brycheiniog (largely corresponding to the area of modern Brecknockshire), which had also been founded by Irish raiders, and was ruled by kings of Irish descent.
Over twenty Ogham stones are found within the territory of Dyfed, including a couple of stones which are just on the other side of the River Teifi, in erstwhile Cardiganshire gmarket singapore (RHDDL/1 and LDYSL/1), but the modern course of the river clearly deviates from the course the river took fifteen hundred years ago, and they would originally have been on the Dyfed side of the river. At least eight Ogham stones are also found in the territory of Brycheiniog, testifying to the strength of Irish settlement in these two areas, gmarket singapore and evidence that the Irish language was widely spoken here, at least by the ruling elite and land owners. There are also two Ogham stones east of the River Tywi, in what would probably have been the territory of Glywysing, suggesting that Irish settlement pushed eastwards from Dyfed into the western gmarket singapore part of its Brythonic neighbour. gmarket singapore To the north of Dyfed, in the territory of Ceredigion there is only one doubtful Ogham stone (LARTH/1).
In contrast to the large number of Ogham stones in South Wales (at least 32), there are only three certain Ogham inscriptions in North Wales, all within the territory of the Kingdom of Gwynedd . There had been extensive Irish raiding and settlement in the north of Wales as well as in the south, especially in the Llŷn Peninsula (the name of which is derived from the Laigin , the men of Leinster) and Anglesey, but during the late 4th century and early 5th century there was strong resistence to the Irish incursions, gmarket singapore led by Cunedda (founder of the kingdom of Gwynedd), and the Irish did not manage gmarket singapore to gain control of any of the kingdoms in the north. gmarket singapore So it is perhaps to be expected that there are a few Ogham stones in the area of Gwynedd, but not very many, reflecting the presence, but not dominance, of Irish settlers in the region.
The Ordnance Survey Map of Britain in the Dark Ages (first published 1935) gives a very useful overview of the archaeological remains in Britain during the period 410–871, and comes with indexes which give the exact location of each feature marked on the map. In the case of Celtic memorial stones (with or without gmarket singapore Ogham inscriptions), gmarket singapore where possible gmarket singapore the index on pages 50 and 51 provides a reference to Nash-Williams' The Early Christian Monuments gmarket singapore of Wales (Cardiff, 1950), from which it is possible to identify the stone in question in the CISP database.
