As promised last week, here is the superb talk which Dr Emily Thelen gave last Monday about devotion to the Seven Sorrows of the Virgin in the Low Countries in the later 15th centuries, and an important manuscript that contains a very beautiful Mass composed for that feast. This talk was held as part of an ongoing lecture series offered by the Catholic Institute of Sacred Music; the next one in the series will be on Tuesday, November 7th, at 5:45 pm Pacific.
