The Juniper Passion is a 2011 opera by New Zealand composer Michael F. Williams to a libretto by John Davies. The opera is set in 1944 during the World War II Battle of Monte Cassino, an Allied victory, but with a loss of life totalling approximately 105,000 deaths, including many New Zealand soldiers, over the series of battles. "The Juniper Passion" is written in three acts, six principal roles and chorus and is scored for chamber orchestra with digital effects. Performance is through dance with only minimal movement and interaction by the singing cast. In place of traditional sets, the opera has a 3-D computer graphic set design by Sean Castle that recreates the Benedictine abbey at Cassino. This is interspersed with images taken during the battle by Richard Ferguson Davies, father of librettist John Davies.
