Nicholas Yasillo's wife was much taken with medieval-era decorated volumes of prayers and religious scenes, known as the Book of Hours. As such, he commissioned Garrop for a work in her honor. Garrop appropriately uses her String Quartet No. 4 to describe not just five scenes from The Hours by Catherine of Cleves (c. 1400's), but a reading of the book and personal discovery of each illustration (Illuminations). The work was written for the Cecilia Quartet, who gave the premiere in September, 2011. For advanced perfomers. Dur.: 19'
