Razos and Troubadour Songs [PDF ebook] 

Originally published in 1990, this book contains the full text and translation of razos and troubadour songs. The coupling of the razos and songs in this edition is based on the conviction that though the lyrics should first be read on their own, it is highly instructive to read the two together, as the razo authors intended. This allows the reader to attempt to read as a thirteenth-century contemporary might have.
