Ath Cliath section We have a bit of a problem here as the Irish name Baile atha Cliath was first written down in 1368 in the Annals of Ulster The other sources mentioned such as the Annals of the Four Masters were written down even later In other words we don t know what it was called before it was called Duiblinn Dyflin and to name a whole section Ath Cliath is fanciful at best I m renaming it Pre Viking Dublin unless anyone can come up with better Some will say it is likely that it was called BAC before 795 others that it is just as likely that the Vikings copied Dubh Linn
