Another source quotes the Annals of the Four Masters as dating the establishment of the Oenach Tailten to the "year of the world 3370." Subsequently it was reported occurring in "A.D. 539, 594, 715, 806, 825, 847, 855, 887, 894, 903, 914, 915, 925, 1001, 1004, 1006, 1120, & 1168." (Petrie, George. "Aspects of George Petrie. V. An Essay on Military Architecture in Ireland Previous to the English Invasion." Proceedings of the Royal Irish Academy. Polite Literature and Antiquities 72 (1972 (read 1834): 236.)
According to D.A.

"The Fair of Tailtiu and the Feast of Tara." Ériu 18 (1958): 113-38.)
