French Baroque composer Marc-Antoine Charpentier (1643?-1704) studied under Italian sacred music composer Giacomo Carissimi and wrote for Molière's theatre company. Only one opera, Médée, survives from this period. The final twenty years of his life were spent mainly with sacred music. Noted achievements in this genre include a famous setting of the Te Deum, the beautiful Christmas Midnight Mass and the Assumpta est Maria Mass.
