Missa Cellensis in honorem Beatissimae Virginis Mariae No.3 in C major, Hob. XXII:5 "Cäcilienmesse/ Cacilienmesse"

The Missa Cellensis in honorem Beatissimae Virginis Mariae in C major by Joseph Haydn, Hob. XXII:5, Novello 3, was originally written in 1766, after Haydn was promoted to Kapellmeister at Eszterháza following the death of Gregor Joseph Werner. The original title as it appears on the only surviving fragment of Haydn's autograph score, that has been discovered around 1970 in Budapest, clearly assigns the mass to the pilgrimage cult of Mariazell, Styria. Until that discovery, the work was formerly known as Missa Sanctae Caeciliae, or in German Cäcilienmesse, a title probably attributed to the mass in the 19th century. Whether the alternative title refers to a performance of the piece by the St. Cecilia's Congregation, a Viennese musician's fraternity, on some St. Cecilia's day (22 November), as has been suggested, remains speculation.
