Commentary
Stewart Baldwin: Since Iago apparently died only 18 years (or thereabouts) before his grandson Cadwallon, he was evidently elderly at the time. Thus, as has been pointed out on numerous occasions, there are chronological difficulties with accepting his traditional pedigree [HG.1: "... Iacob map Beli map Rhun map Mailcun ..."], which would make him the great-grandson of the famous Maelgwn Gwynedd, king of Gwynedd, and contemporary of Gildas, who is frequently dated to the middle of the sixth century (perhaps not correctly). Despite these doubts, the traditional genealogy of Iago is not absolutely impossible, even if Maelgwn died in the middle of the sixth century. Furthermore, since the AC obituary of Maelgwn has been convincingly shown to be a tenth century fabrication (see "Gildas and Maelgwn: Problems of Dating", by David N. Dumville, in Gildas: New Approaches (ed. Lapidge & Dumville, The Boydell Press), 51-9), it is not impossible that both Gildas and Maelgwn should be dated earlier in the sixth century, which would ease the chronological problems caused by the above genealogy. Thus, if a consensus should arise that the work of Gildas should be dated a generation or so earlier than it normally has been, the skeptical position on these earlier generations might have to be reevaluated'
