Lewis Spence,
Legends & Romances of Brittany
“ The Brezonek, the Brythonic tongue of Brittany, is undoubtedly the language of those Celtic immigrants who fled from Britain the Greater to Britain the Less to escape the rule of the Saxon invaders, and who gave the name of the country which they had left to that Armorica in which they settled. In the earliest stages of development it is difficult to distinguish Breton from Welsh. From the ninth to the eleventh centuries the Breton language is described as ‘Old Breton.’ ‘Middle Breton’ flourished from the eleventh to the seventeenth centuries, since when ‘Modern Breton’ has been in use. ”
