Commentary
Stewart Baldwin: 'Agricola (Aergul Lawhir), king of Demetia (Dyfed) (a good king, according to Gildas) [HG.2: "Aircol map Triphun"; ED] [Note: His reign as king of Dyfed is confirmed by the contemporary testimony of Gildas, who, although he does not provide his name, calls his son Uortiporius the bad son of a good king. His name comes from the later sources, of which HG is the earliest. His chronology is very uncertain, due to the uncertain timeframe of Gildas, but the late fifth century would be a reasonable estimate. Agricola was of Irish descent, a member of the tribe known as the Déisi, a segment of which moved from Ireland to Wales at an uncertain date, and eventually became rulers of Dyfed. His claimed father Tryffin (Triphun), if accurately remembered, is nothing more than a name, and there are significant disagreements in the genealogy prior to Tryffin. If it can be accepted that they hide a grain of truth, it is at least arguable that Agricola's grandfather was a man who was nicknamed "Briscus" (Irish "Brosc", Welsh "Vreisc"). See DGD and DD for detailed discussions. It should be noted that the larger generation number for Agricola and his immediate descendants is due to the fact that the dynasty of Dyfed appears to have had a somewhat smaller average number of years per generation that the other lines followed (but not enough smaller to cause suspicion), and that Agricola was probably a rough contemporary of the Irish men who appear in generations 22 or 23.]'
