Volume 4 of The Complete Works of Geoffrey Chaucer edited by Reverend Walter W. Skeat. This book includes the complete Canterbury Tales in the original Middle English with extensive notes, published by Oxford University in 1900. According to Wikipedia: Geoffrey Chaucer (c. 1343 – 1400?) was an English author, poet, philosopher, bureaucrat, courtier and diplomat. Although he wrote many works, he is best remembered for his unfinished frame narrative The Canterbury Tales. Sometimes called the father of English literature, Chaucer is credited by some scholars as the first author to demonstrate the artistic legitimacy of the vernacular English language, rather than French or Latin.
