A new edition of an invaluable collection of literary sources, all in translation, for Celtic Europe and early Ireland and Wales. The selections are divided into three sections: the first is classical authors on the ancient celts-a huge selection including both the well-known-Herodotos, Plato, Aristotle, Livy, Diogenes Laertius, and Cicero-and the obscure-Pseudo-Scymnus, Lampridius, Vopsicus, Clement of Alexandria and Ptolemy I. The second is early Irish and Hiberno-Latin sources including early Irish dynastic poetry and numerous tales from the Ulster cycle and the third consists of Brittonic sources, mostly Welsh.
