Delitiae Testudinis ( Delights of the Lute ) is the first in a series of books for lute and chamber ensemble that Reusner published in his short, brilliant career. Apart from its extraordinary merit on artistic grounds, and its admirable baroque calligraphy, the book occupies an important place in the history of lute music, coming after many decades of strife in Europe defined by war and depressed economic & cultural activity.
