David Rowe, Proverbs of Middle-earth at Oloris Publishing, and at Amazon, at each location for $18.00.
From the publisher's description:
The works of JRR Tolkien are unique in English Literature, as they are filled with hundreds of original proverbs. 'Not all those who wander are lost,' 'Faithless is he that says farewell when the road darkens,' and 'Never laugh at live dragons' are all poetic, wise, and convincingly real-sounding, but they are also a lens, through which more can be seen. These proverbs belong to entirely invented wisdom traditions and reflect the culture, the philosophical worldview, and the history of those who use them.
