Beneventan and Milanese Chant
Thomas Forrest Kelly
In 1058 Pope Stephen IX visited Montecassino, of which he had been made abbot only shortly before his elevation to the papacy previous year. This German was former papal chancellor Frederick Lorraine, second northern Montecassino. On occasion this visit strictly forbade singing at Montecassino ‘Ambrosian chant’: ‘Tune etiam et Ambrosianum cantum in ecclesia ista cantari penitus interdixit.’
