 In the "Saga of Harald Hårfagre", Snorri tells us that Þorgils ruled his newly conquered domains from Dublin, and that he was "a long time king over Dublin".In the "Annals of Ulster", however, Turgéis is only mentioned in connection with an encampment on Lough Ree in 845.It is likely that his role in history was greatly exaggerated by later chroniclers and that he played no direct part in the foundation of Viking Dublin.
