Mottetto natalizio a 8 voci (doppio coro SATB) del compositore bolognese Girolamo Giacobbi (1567-1629), maestro di Adriano Banchieri e maestro di cappella per oltre 20 anni in San Petronio, anche se maggiormente conosciuto per le sue opere liriche che per la sua produzione sacra.

A Christmas motet for double SATB choir by Girolamo Giaccobbi, Adriano Banchieri's teacher in Bologna at the end of the 16th century. He was more known for his secular compositions than for sacred music such as this motet, although he directed the music in St.Petronio for over 20 years.
