Note 6 — Chapter IV

Dr. Whitley Stokes' "Tripartite Life of St. Patrick," vol. i. p. cxxix. "That Tighearnach had access to some library or libraries furnished with books of every description is manifest from his numerous references; and the correctness of his citations from foreign authors, with whose works we are acquainted may be taken as a surety for the genuineness of his extracts from the writings of our own native authors now lost." For the non-Irish portions of his annals Tighearnach used, as Stokes has shown, St. Jerome's "Interpretatio Chronicæ Eusebii Pamphili," the seven books of the history of Paulus Orosius, "The Chronicon, or Account of the Six Ages of the World," in Bede's Works, "The Vulgate," "The Etymologarium," "Libri XX of Isodorus Hispalensis," Josephus' "Antiquities of the Jews," probably in a Latin translation, and perhaps the lost Chronicon of Julius Africanus.
