The Ambrosian Liturgy, better perhaps than any other, preserved traces of the great vigils or "pannychides", with their complex and varied display of processions, psalmodies, etc. The same liturgy also preserved vigils of long psalmody. This nocturnal office adapted itself at a later period to a more modern form, approaching more and more closely to the Roman liturgy. Here too were found the three nocturns, with Antiphon, psalms, lessons, and responses, the ordinary elements of the Roman matins, and with a few special features quite Ambrosian.
